S-8365/8366 Series www.ablic.com www.ablicinc.com STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER Rev.2.1_02 © ABLIC Inc., 2009-2015 The S-8365/8366 Series is a CMOS step-up switching regulator controller which mainly consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a timer latch short-circuit protection circuit, a PWM control circuit (S-8365 Series) and a PWM / PFM switching control circuit (S-8366 Series). With an external low-ON-resistance Nch Power MOS FET, this product is ideal for applications requiring high efficiency and a high output current. The S-8365 Series efficiently works on voltage’s condition of large I/O difference due to the PWM control circuit linearly varies the duty ratio to 90%. During light-load, the S-8366 Series switches its operation to the PFM control by the PWM / PFM switching control circuit in order to prevent efficiency decline due to the IC operating current. Ceramic capacitors can be used for output capacitor. Small packages SNT-6A, SOT-23-5 and SOT-23-6 enable high-density mounting.  Features  Low operation voltage  Input voltage range  Oscillation frequency  Reference voltage  Soft start function  Low current consumption  Duty ratio  Shutdown function  External parts  Timer latch short-circuit protection circuit  UVLO (under-voltage lockout) function  Lead-free, Sn 100%, halogen-free*1 : Start at 1.1 V (1 mA) guaranteed (in the product without UVLO function) : 1.8 V to 5.5 V : 1.2 MHz, 600 kHz : 0.6 V2.0% : 7 ms typ. : 70 A typ. at switching off : Built-in PWM / PFM switching control circuit (S-8366 Series) 28% to 85% (1.2 MHz product) 28% to 90% (600 kHz product) : Current consumption 1.0 A max. at shutdown : Inductor, diode, capacitor, transistor : Selectable with / without short-circuit protection circuit for each product Settable delay time by external capacitor (in the product with short-circuit protection) : Selectable with / without UVLO for each product *1.

Switching control method 1.1 PWM control (S-8365 Series) The S-8365 Series is a switching regulator controller that uses a pulse width modulation method (PWM). In conventional PFM control switching regulators, pulses are skipped when the output load current is small, causing a fluctuation in the ripple frequency of the output voltage, resulting in increased ripple voltage. For the S-8365 Series, although the pulse width changes from 0% to 90% in accordance with each load current (or 0% to 85% for 1.2 MHz products), since the switching frequency does not change, the ripple voltage generated due to switching can be eliminated by filtering. The ripple voltage can thus be lowered in the wide input voltage and load current ranges. 1.2 PWM / PFM switching control (S-8366 Series) The S-8366 Series switching regulator controller automatically switches between the pulse width modulation method (PWM) and pulse frequency modulation method (PFM) according to the load current. A low ripple power can be supplied by operating on PWM control for which the pulse width changes from 28% to 90% (or 28% to 85% for 1.2 MHz products) in the range where the output load current is large. The S-8366 Series operates on PFM control when the output load current is small and the fixed pulses which have the width of 28% are skipped according to the load current amount. Therefore, the oscillation circuit intermittently oscillates, reducing the self-current consumption. This avoids decreased efficiency when the output load current is small. The point at which PWM control switches to PFM control varies depending on the external element (inductor, diode, etc.), input voltage value, and output voltage value, and this method achieves high efficiency in the output load current of about 100 A. 2. Soft-start function The S-8365/8366 Series has a soft-start circuit. The output voltage (VOUT) gradually rises after power-on or startup when the ON/OFF pin is set to high, suppressing rush current and overshooting the output voltage. The soft-start time (tSS) for the S-8365/8366 Series is defined as the time from startup until VOUT reaches 90% of the output set voltage value (VOUT(S)). A reference voltage adjustment method is used as the soft-start method and the reference voltage gradually rises from 0 V after soft-start. A soft-start performs by controlling the FB pin voltage so that it follows the rise of the reference voltage. After the reference voltage rises once, it is reset to 0 if the ON/OFF pin voltage drops to low, the power supply voltage drops to the UVLO detection voltage, or the S-8365/8366 Series enters the short-circuit protection latch status. A soft-start is performed regardless of conditions when resuming step-up operation. 14 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER Rev.2.1_02 S-8365/8366 Series 3. Shutdown pin This pin stops or starts step-up operations. 3.1 Without ON/OFF pin pull-down When this pin is set to the low level, the voltage of the EXT pin is fixed to 0 V, and the external transistor and all internal circuits stop, substantially reducing the current consumption. Do not use the ON/OFF pin in a floating state because it is set up as shown in Figure 11 and is not internally pulled up or down. Do not apply a voltage of between 0.3 V and 0.75 V to the ON/OFF pin because applying such a voltage increases the current consumption. If the ON/OFF pin is not used, connect it to the VDD pin.

VDD ON/OFF VSS Figure 11 3.2 With ON/OFF pin pull-down When the ON/OFF pin is set to the low level, the voltage of the EXT pin is fixed to 0 V, and the external transistor and all internal circuits stop substantially reducing the current consumption. The ON/OFF pin is set up as shown in Figure 12 and is internally pulled down by using the depression transistor, so all circuits stop even if this pin is floating. Do not apply a voltage of between 0.3 V and 0.75 V to the ON/OFF pin because applying such a voltage increases the current consumption. If the ON/OFF pin is not used, connect it to the VDD pin.

Timer latch type short-circuit protection (products with short-circuit protection function) The S-8365/8366 Series incorporates a timer latch type short-circuit protection circuit that stops switching operation if the output short circuits for a certain time or more. Connect a capacitor (CSP) to the CSP pin to set the delay time of this circuit. The S-8365/8366 Series operates on the maximum duty if the output voltage drops due to output short-circuiting or other factors. When it enters the maximum duty status, charging the constant current to CSP is started. If this status is held for the short-circuit protection delay time or more, the voltage of the CSP pin exceeds the reference voltage and the IC enters the latch mode. Note that switching operation stops in latch mode but the internal circuits normally operate, which differs from the power-off status. The constant current is continuously charged to CSP even in latch mode, so the voltage of the CSP pin rises to the VDD level. To reset the latch mode of short-circuit protection, lower VDD to the UVLO detection voltage or lower or set the ON/ OFF pin to the low level.

UVLO function (products with UVLO function) The S-8365/8366 Series has a UVLO (undervoltage lockout) circuit for avoiding IC malfunctions due to power supply voltage drops. The S-8365/8366 Series stops switching operation upon UVLO detection and retains the external transistor in the off state. After entering the UVLO detection status once, the soft-start function is reset. Note, however, that the other internal circuits operate normally and that the status differs from the power-off status. 16 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER Rev.2.1_02 S-8365/8366 Series  Operation Principles The S-8365/8366 Series is a step-up switching regulator controller. Figure 14 shows the basic circuit diagram. Step-up switching regulators start current supply by the input voltage (VIN) when the Nch power MOS FET is turned on and holds energy in the inductor at the same time. When the Nch power MOS FET is turned off, the CONT pin voltage is stepped up to discharge the energy held in the inductor and the current is discharged to VOUT through the diode. When the discharged current is stored in CL, a voltage is generated, and the potential of VOUT increases until the voltage of the FB pin reaches the same potential as the internal reference voltage. For the PWM control method, the switching frequency (fOSC) is fixed and the VOUT voltage is held constant according to the ratio of the ON time and OFF time (ON duty) of the Nch power MOS FET in each period. For the PWM control method, the VOUT voltage is held constant by controlling the ON time. In the S-8366 Series, the Nch power MOS FET is turned on when the fixed duty cycle is 28% for the PFM control method. When energy is discharged to VOUT once and the VOUT potential exceeds the set value, the Nch power MOS FET stays in the off status until VOUT decreases to the set value or less due to the load discharge. Time VOUT decreases to the set value or less depends on the amount of load current, so, the switching frequency varies depending on this current. CONT L IOUT I2 SD VOUT VIN I1 Nch power MOS FET EXT FB COUT VSS Figure 14 RL Basic Circuit of Step-up Switching Regulator The ON duty in the current continuous mode can be calculated by using the equation below. Use the S-8365/8366 Series in the range where the ON duty is less than the maximum duty. Note that the products with short-circuit protection is set in the timer-latch status if the maximum duty lasts the short-circuit protection delay time (tPRO) or more. The maximum duty is 85% typ. for 1.2 MHz products and 90% for 600 kHz products. ON duty = (1  VIN VOUT + VD*1 )  100 [%] The ON time (tON) can be calculated by using the following equation : 1  ON duty tON = f OSC VIN 1 =  1 ······ (1) V + VD*1 OUT f OSC ( ) *1.

Continuous current mode The following explains the current that flows into the inductor when the step-up operation stabilizes in a certain status and IOUT is sufficiently large. When the Nch power MOS FET is turned on, current (I1) flows in the direction shown in Figure 14. The inductor current (IL) at this time gradually increases in proportion with the ON time (tON) of the Nch power MOS FET. Current change of inductor within tON : IL(ON) = IL max.  IL min. VIN = L  tON When the Nch power MOS FET is turned off, the voltage of the CONT pin is stepped up to VOUT + VD and the voltage on both ends of the inductor becomes VOUT + VD  VIN. However, it is assumed here that VOUT >> VD and VD is ignored. Current change of inductor within tOFF : VOUT  VIN IL(OFF) =  tOFF L The input power equals the output power in an ideal situation where there is no loss by components. IIN(AV) : PIN = POUT IIN(AV)  VIN = IOUT  VOUT VOUT  IOUT .................. (2) IIN(AV) = V IN The current that flows in the inductor consists of a ripple current that changes due to variation over time and a direct current. From Figure 15 : IIN(AV) : IL 2 VOUT  VIN = IIN(DC) +  tOFF 2L VIN = IIN(DC) +  tON.......... (3) 2L IIN(AV) = IIN(DC) + Above, the continuous mode is the operation mode when IIN(DC) > 0 as shown in Figure 15 and the inductor current continuously flows. While the output current (IOUT) continues to decrease, IIN(DC) reaches 0 as shown in Figure 16. This point is the critical point of the continuous mode. As shown in equations (2) and (3), the direct current component (IIN(DC)) depends on IOUT. IOUT(0) when IIN(DC) reaches 0 (critical point) : IOUT(0) = tON  VIN2 2  L  VOUT tON can be calculated using equation (1). When the output current decreases below IOUT(0), the current flowing in the inductor stops flowing in the tOFF period as shown in Figure 17. This is the discontinuous mode. 18 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER Rev.2.1_02 S-8365/8366 Series IL IL max. IIN(AV) IL min.

Inductor The recommended L value of the S-8365/8366 Series is 2.2 H for 1.2 MHz products and 3.3 H for 600 kHz products. Note the following when changing the inductance. The inductance (L) has a strong influence on the maximum output current (IOUT) and efficiency (). The inductor peak current (IPK) increases when L is decreased, which improves the circuit stability and increases the IOUT users can obtain. If L is decreased further, the ability of the external transistor to drive the current becomes insufficient, reducing the efficiency and decreasing IOUT. The loss due to the IPK of the switching transistor is decreased by increasing L and the efficiency maximizes at a certain L value. If L is increased further, the loss due to the serial resistance of the inductor increases, lowering the efficiency. Caution When selecting an inductor, be careful about its allowable current. If a current exceeding the allowable current flows through the inductor, magnetic saturation occurs, substantially lowering the efficiency and destroying ICs due to large current. Therefore, select an inductor such that IPK does not exceed the allowable current. The following equations express IPK in the ideal statuses in the discontinuous and continuous modes : 2  IOUT  (VOUT + VD*2  VIN) fOSC*1  L *2 VOUT + VD (VOUT + VD*2  VIN)  VIN  I IPK = OUT + VIN 2  (VOUT + VD*2)  fOSC*1  L IPK = *1. *2. (Continuous mode) fOSC : oscillation frequency VD is the forward voltage of a diode. The reference value is 0.4 V. However, current exceeding the above equation flows because conditions are practically not ideal. Perform sufficient evaluation with actual application.

Diode Use an externally mounted that meets the following conditions.  Low forward voltage (Schottky barrier diode or similar type)  High switching speed  Reverse withstand voltage of VOUT + spike voltage or more  Rated current of IPK or more 3. Input capacitor (CIN) and output capacitor (COUT) To improve efficiency, an input capacitor (CIN) lowers the power supply impedance and averages the input current. Select CIN according to the impedance of the power supply used. The recommended capacitance is 10 F for the S-8365/8366 Series. An output capacitor (COUT), which is used to smooth the output voltage, requires a capacitance larger than that of the step-down type because the current is intermittently supplied from the input to the output side in the step-up type. A 22 F ceramic capacitor is recommended for the S-8365/8366 Series. However, a higher capacitance is recommended if the output voltage is high or the load current is large. If the output voltage or load current is low, about 10 F can be used without problems. Select COUT after sufficient evaluation with actual application. A ceramic capacitor can be used for both the input and output. 4. Capacitor for setting short-circuit protection delay time (CSP) (products with short-circuit protection) For the S-8365/8366 Series, the short-circuit protection delay time can be set to any value by using an external capacitor. Connect the capacitor between the CSP and VSS pins. Select the capacitor value according to the equation below and Figure 18. Note, however, that the equation and figure show a theoretical value assuming an ideal capacitor value and typ. IC conditions. Variations of the capacitor and IC are not considered. For the IC variations, see the short-circuit protection delay time (tPRO) in “ Electrical Characteristics”. tPRO [ms]  1.2  103 0.6 120 100 tPRO [ms] CSP [F]  80 60 40 20 0 0 0.05 0.10 0.15 0.20 0.25 CSP [F] Figure 18 CSP vs. tPRO 21 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER Rev.2.1_02 S-8365/8366 Series 5. External transistor A bipolar (NPN) or enhanced (Nch) MOS FET transistor can be used as an external transistor. 5.1 Bipolar NPN type The driving ability to increase output current by using a bipolar transistor is determined based on the hFE value and Rb value of the bipolar transistor. Figure 19 shows the peripheral circuit. VDD Cb 2200 pF Pch EXT Nch Figure 19 IPK Rb 1 k External Transistor Peripheral Circuit The recommended Rb value is around 1 k. Calculate the required base current (Ib) based on the hFE value of IPK , and then select an Rb value smaller than that determined using: the bipolar transistor by using Ib = h FE VDD  0.7 0.4 Rb = - Ib I EXTH Smaller Rb values increase the output current, but decrease the efficiency. Actually, the current might flow on pulses or the VDD or VSS voltage might drop due to wiring resistance, so determine the optimum value based on experimentation. Inserting a speed-up capacitor (Cb) in parallel with the Rb resistor as shown in Figure 19 reduces switching loss and increases efficiency. 1 . Select a speed-up capacitor for which the Cb value satisfies Cb  2    Rb  fOSC  0.7 Actually, however, the optimum Cb value varies depending on the characteristics of the bipolar transistor used, so determine the optimum value based on experimentation. 5.2 Enhanced MOS FET type Use an Nch power MOS FET. A MOS FET that has low ON-resistance (RON) and input capacitance (CISS) is ideal for gaining efficiency. The ON-resistance and input capacitance generally have a tradeoff relationship. ON-resistance is efficient in the range where the output current is high with relatively low frequency switching, and input capacitance is efficient in the range where the output current is medium to low with high frequency switching. Therefore, select a MOS FET for which the ON-resistance and input capacitance are optimum under your usage conditions. The input voltage (VDD) is supplied as the gate voltage of a MOS FET, so select a MOS FET for which the gate withstand voltage is higher than the maximum value used for the input voltage, and for which the drain withstand voltage is greater than or equal to the output voltage (VOUT) + the forward voltage of the diode (VD). If a MOS FET for which the threshold value is near the UVLO detection voltage is used, a high current flows upon power-on, and, in the worst case, the output voltage might not increase and the timer latch type short-circuit protection circuit might operate. Therefore, select a MOS FET for which the threshold value is sufficiently lower than the UVLO detection voltage. 22 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER Rev.2.1_02 S-8365/8366 Series 6. Output voltage setting resistors (RFB1, RFB2), capacitor for phase compensation (CFB) For the S-8365/8366 Series, VOUT can be set to any value by using external divider resistors. Connect the divider resistors between the VOUT and VSS pins. Because VFB = 0.6 V typ., VOUT can be calculated by using the following equation : VOUT = RFB1 + RFB2  0.6 RFB2 Connect divider resistors RFB1 and RFB2 as close to the IC as possible to minimize the effects of noise. If noise has an effect, adjust the values of RFB1 and RFB2 so that RFB1 + RFB2 < 100 k. CFB, which is connected in parallel with RFB1, is a capacitor for phase compensation. By setting the zero point (the phase feedback) by adding capacitor CFB to output voltage setting resistor RFB1 in parallel, the phase margin increases, improving the stability of the feedback loop. To effectively use the feedback portion of the phase based on the zero point, define CFB by using the following equation : CFB  L  COUT VOUT  V 3  RFB1 DD This equation is only a guide. The following explains the optimum setting. To efficiently use the feedback portion of the phase based on the zero point, specify settings so that the phase feeds back at the zero point frequency (fzero) of RFB1 and CFB according to the phase delay at the pole frequency (fpole) of L and COUT. The zero point frequency is generally set slightly higher than the pole frequency. The following equations are used to determine the pole frequency of L and COUT and the zero point frequency set using RFB1 and CFB. 1 VDD  V OUT L  COUT 1 fzero  2    RFB1  CFB fpole  2 The transient response can be improved by setting the zero point frequency in a lower frequency range. If, however, the zero point frequency is set in a significantly lower range, the gain increases in the range of high frequency and the phase margin decreases. This might result in unstable operation. Determine the proper value after sufficient evaluation with actual application. The typical constants based on our evaluation are shown in Table 15.

Perform thorough evaluation using an actual application to set the constants.  Precaution  Mount external capacitors and inductor as close as possible to the IC. Set single point ground.  Characteristics ripple voltage and spike noise occur in IC containing switching regulators. Moreover rush current flows at the time of a power supply injection. Because these largely depend on the inductor, the capacitor and impedance of power supply used, fully check them using an actually mounted model.  The 0.1 F capacitor connected between the VDD and VSS pins is a bypass capacitor. It stabilizes the power supply in the IC when application is used with a heavy load, and thus effectively works for stable switching regulator operation. Allocate the bypass capacitor as close to the IC as possible, prioritized over other parts.  Although the IC contains a static electricity protection circuit, static electricity or voltage that exceeds the limit of the protection circuit should not be applied.  The power dissipation of the IC greatly varies depending on the size and material of the board to be connected. Perform sufficient evaluation using an actual application before designing.  ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party. 25 STEP-UP, SUPER-SMALL PACKAGE, 1.2 MHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER Rev.2.1_02 S-8365/8366 Series  Application Circuits Application circuits are examples.
