S-8533 Series www.ablic.com www.ablicinc.com STEP-DOWN, SYNCHRONOUS PWM CONTROL SWITCHING REGULATOR CONTROLLER © ABLIC Inc., 2002-2010 Rev.3.0_02 The S-8533 Series is a synchronous PWM control CMOS step-down switching regulator controller that includes a reference voltage source, synchronous circuit, oscillation circuit, error amplifier, phase compensation circuit, and PWM controller. An efficient step-down switching regulator can be realized simply by adding external P-channel and N-channel power MOS FETs, one coil, and three capacitors. Since the oscillation frequency is a high 300 kHz, the S-8533 can be used to configure a high efficiency step-down switching regulator capable of driving high output current using small external parts and a 3 to 10% increase in efficiency is obtained compared to conventional step-down switching regulators. The 8-Pin TSSOP package and high oscillation frequency make the S-8533 ideal as the main power supply for portable devices.  Features  Synchronous rectification system realizing high efficiency (typ. 94%)  Use at maximum duty ratio = 100% and use of a battery up to maximum life is possible by using P-channel and Nchannel power MOS FETs externally.  Oscillation frequency : 300 kHz typ.  Input voltage : 2.7 to 16.0 V  Output voltage : 1.25 V 1.3 to 6.0 V, selectable in 0.1 V steps  Output voltage accuracy : 2.0%  Soft-start function set by an external capacitor (CSS)  Shutdown function  Lead-free, Sn 100%, halogen-free*1 *1.

Synchronous PWM Control Step-down DC-DC Converter 1. 1 Synchronous Rectification A synchronous rectifying DC-DC converter enables a greater reduction in the power consumption of the external rectifying element compared with a conventional DC-DC converter. In addition, incorporating a P and N feedthrough prevention circuit reduces the feed-through current during operation of external transistors (P-channel and N-channel), making the operating power consumption extremely low. 1. 2 PWM Control The S-8533 Series is a DC-DC converter that uses pulse width modulation (PWM) and is characterized by its low current consumption. In conventional modulation PFM system DC-DC converters, pulses are skipped when they are operated with a low output load current, causing variations in the ripple frequency of the output voltage and an increase in the ripple voltage. Both of these effects constitute inherent drawbacks to those converters. In the S-8533 Series, the pulse width varies in the range from 0 to 100% according to the load current, yet the ripple voltage produced by the switching can easily be eliminated by a filter since the switching frequency is always constant. When the pulse width is 0% (when there is no load or the input voltage is high), current consumption is low since pulses are skipped. 2. Soft-Start Function The S-8533 Series has a built-in soft-start circuit. This circuit enables the output voltage (VOUT) to rise gradually over the specified soft-start time (tSS) to suppress the overshooting of the output voltage, when the power is switched on or the ON/OFF pin is set “H”. The soft-start time can be set with an external capacitance (CSS). The time needed for the output voltage to reach 95% of the set output voltage value is calculated by the following formula. tSS [ms] = 0.002  CSS [pF] Soft-start time (t SS) [ms] 60 50 40 30 20 10 0 0 5000 10000 15000 External capacitance (CSS) [pF] 20000 Figure 7 Soft-Start Time The value for CSS should be selected to give enough margin to the soft-start time against the power supply rise time. If the soft-start time is short, possibility for output voltage overshoot, input current rush, and malfunction of the IC increases. 9 STEP-DOWN, SYNCHRONOUS PWM CONTROL SWITCHING REGULATOR CONTROLLER Rev.3.0_02 S-8533 Series 3. ON/OFF Pin (Shutdown Pin) This pin is used to activate and deactivate the step-down operation. When the ON/OFF pin is set to “L”, all the internal circuits stop working, and substantial savings in current consumption are thus achieved. The voltage of the PDRV pin goes to VIN level and voltage of the NDRV pin goes to VSS level to shut off the respective transistors. The ON/OFF pin is configured as shown in Figure 8. Since pull-up or pull-down is not performed internally, operation where the ON/OFF pin is in a floating state should be avoided. Application of a voltage of 0.3 to 1.8 V to the pin should also be avoided lest the current consumption increases. When the ON/OFF pin is not used, it should be connected to the VIN pin. VIN ON/OFF Pin CR Oscillation Circuit Output Voltage “H” “L” Active Non-active Set value Open ON/OFF VSS Figure 8 ON/OFF Pin Structure 4. 100% Duty Cycle The S-8533 Series operates with a maximum duty cycle of 100%. The switching transistor can be kept on to supply current to the load continually, even in cases where the input voltage falls below the preset output voltage value. The output voltage under these circumstances is equal to the subtraction of the lowering due to the DC resistance of the coil and the on-resistance of the switching transistor from the input voltage. 5. Back-Flow Current Since the S-8533 Series performs PWM synchronous rectification under a light load, current flows backward in the VIN direction. The back-flow current therefore reaches its peak when there is no load (see Figure 9). Pay attention to the maximum back-flow current value, which can be calculated from the following expressions. Duty (IOUT = 0) = VOUT/VIN Example : VIN = 5 V, VOUT = 3 V, Duty = 60% IL = V/L  ton = (VIN  VOUT)  Duty/(L  fOSC)  1.2 Example : VIN = 5 V, VOUT = 3 V, fOSC = 300 kHz, L = 22 H, IL = 218 mA ILmax. = IL/2 = 109 mA, ILmin. = IL/2 = 109 mA When there is no load, the current waveform becomes a triangular wave with the maximum, ILmax., and the minimum, ILmin., which is negative. The negative current, shaded regions in Figure 10, flows backward. When the output current (IOUT) is approximately 109 mA under the above conditions, the current does not flow backward since the minimum value (ILmin) of the triangular wave becomes 0 mA. When an input capacitor (CIN) is installed, back-flow current to the power source is negligible since the back-flow current is absorbed by the input capacitor. The input capacitor is indispensable to reduce back-flow current to the power source. 10 STEP-DOWN, SYNCHRONOUS PWM CONTROL SWITCHING REGULATOR CONTROLLER Rev.3.0_02 S-8533 Series Though the conditions mentioned above are required to prevent back-flow current, they are guidelines.

Inductor The inductance value (L) greatly affects the maximum output current (IOUT) and the efficiency (). As the L value is reduced gradually, the peak current (IPK) increases, the stability of the circuit is improved, and IOUT increases. As the L value is made even smaller, the efficiency is lowered, and IOUT decreases since the current driveability of the switching transistor is insufficient. As the L value is increased, the dissipation in the switching transistor due to IPK decreases, and the efficiency reaches the maximum at a certain L value. As the L value is made even larger, the efficiency degrades since the dissipation due to the series resistance of the coil increases. IOUT also decreases. An inductance of 22 H is recommended for the S-8533 Series. When choosing an inductor, attention to its allowable current should be paid since the current exceeding the allowable value will cause magnetic saturation in the inductor, leading to a marked decline in efficiency and the breakdown of the IC due to large current. An inductor should therefore be selected so that IPK does not surpass its allowable current. IPK is expressed by the following equation : IPK  IOUT  VOUT  (VIN  VOUT) 2  fOSC  L  VIN where fOSC (= 300 kHz) is the oscillation frequency. 2. Capacitors (CIN, COUT) The capacitor (CIN) inserted on the input side serves to lower the power impedance, average input current, and suppress back-flow current to the power source. Select the CIN value according to the impedance of the power supplied, and select a capacitor that has low ESR (Equivalent Series Resistance) and large capacitance. It should be approximately 47 to 100 F, although the actual value depends on the impedance of the power source used and load current value. When the input voltage is low and the load is large, the output voltage may become unstable. In this case, increase the input capacitance. For the output side capacitor (COUT), select a large capacitance with low ESR (Equivalent Series Resistance) to smoothen the ripple voltage. When the input voltage is extremely high or the load current is extremely large, the output voltage may become unstable. In this case, the unstable area will become narrow by selecting a large capacitance for an output side capacitor. A tantalum electrolytic capacitor is recommended since the unstable area widens when a capacitor with a large ESR, such as an aluminum electrolytic capacitor, or a capacitor with a small ESR, such as a ceramic capacitor, is chosen. The range of the capacitance should generally be approximately 47 to 100 F. Fully evaluate input and output capacitors under the actual operating conditions to determine the best value. 12 STEP-DOWN, SYNCHRONOUS PWM CONTROL SWITCHING REGULATOR CONTROLLER Rev.3.0_02 S-8533 Series 3. External Transistor Enhancement (P-channel, N-channel) MOS FETs can be used as external switching transistors for the S-8533 Series. 3. 1 Enhancement (P-channel, N-channel) MOS FET The PDRV/NDRV pin of the S-8533 Series is capable of directly driving a P-channel or N-channel MOS FET with a gate capacity around 1000 pF. When P-channel/N-channel MOS FETs are chosen, efficiency will be 2 to 3% higher than that achieved by a PNP/NPN bipolar transistor since MOS FET switching speeds are higher than PNP/NPN bipolar transistors and power dissipation due to the base current is avoided. The important parameters in selecting MOS FETs include the threshold voltage, breakdown voltage between gate and source, breakdown voltage between drain and source, total gate capacity, on-resistance, and the current ratings. The PDRV and NDRV pins swing from voltage VIN over to voltage VSS. If the input voltage is low, a MOS FET with a low threshold voltage has to be used so that the MOS FET will turn on as required. If, conversely, the input voltage is high, select a MOS FET whose gate-source breakdown voltage is higher than the input voltage by at least several volts. Immediately after the power is turned on, or when the power is turned off (that is, when the step-down operation is terminated), the input voltage will be imposed across the drain and the source of the MOS FET. The transistor therefore needs to have drain-source breakdown voltage that is also several volts higher than the input voltage. The total gate capacity and the on-resistance affect the efficiency. The power dissipation for charging and discharging the gate capacity by switching operation will affect the efficiency especially at low load current region when the total gate capacity becomes larger and the input voltage becomes higher. If the efficiency under light loads is a matter of particular concern, select a MOS FET with a small total gate capacity. In regions where the load current is high, the efficiency is affected by power dissipation caused by the on-resistance of the MOS FET. If the efficiency under heavy loads is particularly important in the application, choose a MOS FET with as low an on-resistance as possible. As for the current rating, select a MOS FET whose maximum continuous drain current rating is higher than IPK. If an external P-channel MOS FET has much different characteristics (input capacitance, threshold value, etc.) from an external N-channel MOS FET, they turn ON at the same time, flowing a through current and reducing efficiency. If a MOS FET with a large input capacitance is used, switching dissipation increases and efficiency decreases. If it is used at several hundreds of mA or more, the dissipation at the MOS FET increases and may exceed the permissible dissipation of the MOS FET. To select P-channel and N-channel MOS FETs, evaluate the performance by testing under the actual condition. Caution If the load current is large, the P-channel MOS FET dissipation increases and heat is generated. Pay attention to dissipate heat from the P-channel MOS FET. Efficiency data using Sanyo Electric Co., Ltd. CPH6303, CPH6403, and Vishay Siliconix Si3441DV and Si3442DV for applications with an input voltage range of 6 to 8 V or less is included for reference.

Refer to “ Reference Data”. Current flow in the parasitic diode is not allowed in some MOS FETs. In this case, a Schottky diode must be connected in parallel to the MOS FET. The Schottky diode must have a low forward voltage, a high switching speed, a reverse-direction withstand voltage of VIN or higher, and a current rating of IPK or higher. 13 STEP-DOWN, SYNCHRONOUS PWM CONTROL SWITCHING REGULATOR CONTROLLER Rev.3.0_02 S-8533 Series  Standard Circuit  Using MOS FET VOUT L Pch Power MOS FET Nch Power MOS FET 1 8  VON / OFF 4 CSS S-8533 CIN  VIN COUT 5 Figure 11 Caution The above connection diagram does not guarantee correct operation.

However, if the external Pchannel MOS FET has much different characteristics (input capacitance, Vth, etc.) from the external N-channel MOS FET, they may turn ON at the same time, flowing a through current. Select P-channel and N-channel transistors with similar characteristics.  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 coil, the capacitor and impedance of power supply used, fully check them using an actually mounted model.  If the input voltage is high and output current is low, pulses with a low duty ratio may be output, and then the duty ratio may be 0% for several clocks.  The PDRV and NDRV oscillation frequencies may be an integer fraction of 300 kHz at some input voltage and load conditions. In this case, the ripple voltage may increase.  The through current prevention circuit reduces through current by shifting the P-channel and N-channel transistor on timing. It does not suppress the through current in the external transistors completely.  Since PWM synchronous rectification is performed even when the load is light, current flows back to VIN. Check whether the back-flow occurs and whether it affects the performance. (See “5. Back-Flow Current” in “ Operation”.)  The PDRV or NDRV oscillation frequency may vary in a voltage range, depending on input voltage.  When decreasing the power supply voltage slowly, the IC operation may be undefined if the voltage falls below the minimum operating voltage.  Make sure that dissipation of the switching transistor especially at high temperature will not surpass the power dissipation of the package.  Switching regulator performance varies depending on the design of PCB patterns, peripheral circuits and parts.
