Basic Functions / Features Error Amplifier Section (ER AMP) 1.245V±1.6% (Ta= 40°C to +105°C) precise reference voltage is connected to the non-inverted input of this section. To set the output voltage, connects converter's output to inverted input of this section (FB pin). If requiring output voltage of more than 1.245V, should insert resistor divider. Because the optimized compensation circuit is built-in, the application circuit can be composed of minimum external parts. PWM Comparator Section (PWM), Oscillation Circuit Section (OSC) The NJW1616 is a constant frequency, current mode step down regulator. The oscillation frequency is 500kHz (typ.) (A-version). The PWM signal is output by feedback of output voltage and slope compensation switching current at the PWM comparator block. The maximum duty ratio is 94% (typ.). Table 1. Minimum ON time of NJW1616 NJW1616F1-AT Product Name (fOSC =500kHz) Minimum 100ns (typ.) ON-time The ON time of buck converter is decided with the following equation. ton VOUT s VIN fOSC VIN means the input voltage and VOUT means the output voltage. When the ON time becomes below tON-min, in order to maintain the stable output voltage, change of duty or pulse skip operation may be performed. Power MOSFET (SW Output Section) The power is stored in the inductor by the switch operation of built-in power MOSFET. The output current is limited to 0.8A (min.) the overcurrent protection function. In case of step-down converter, the forward direction bias voltage is generated with inductance current that flows into the external regenerative diode when MOSFET is turned off. The SW pin allows voltage between the VIN pin and the SW pin up to +25V. However, you should use an Schottky diode that has low saturation voltage. Power Supply, GND pin (VIN and GND) Along with switching element drive according to oscillation frequency, a transient current flows into the NJW1616. If the power supply impedance of the power supply circuit is large the input voltage fluctuation occurs. As the result, it will not be possible to take sufficient advantage of the NJW1616 performance. Therefore, you should insert a bypass capacitor close to the VIN pin and the GND pin in order to lower high frequency impedance. - 10 - Ver.2016-03-01 NJW1616 Application Manual NJW1616-T Technical Information Description of Block Features (Continued) 2. Additional and Protection Functions / Features Under Voltage Lockout (UVLO) The NJW1616 includes an undervoltage lockout to prevent switching when VIN is less than 4.35V (typ.). The NJW1616 has 100mV (typ.) width hysteresis voltage at rise and decay of power supply voltage. The hysteresis prevents the malfunction at the time of UVLO operating and releasing. Soft Start Function (Soft Start) The SHDN pin can be used to soft-start the NJW1616, reducing the maximum input current during start up. The SHDN pin is driven through an external RC filter to create a voltage ramp at this pin. By adjusting the RC time constant, the peak start up current can be reduced to the current that is required to regulate the output, with no overshoot. And the soft-start operation is able to adjust, too. Moreover, the switching current limit value is limited by applied voltage to the SHDN pin. When the applying voltage is 2.3V, ILIM becomes maximum spec. (Refer to "Switching Current Limit vs.SHDN Pin Voltage" characteristics on ELECTRICAL CHARACTERISTICS) Choose the value of the resistor so that it can supply 20μA or more when the SHDN pin reaches 2.3V.

The overcurrent protection circuit is able to decrease heat generation at the overload. The NJW1616 output returns automatically along with release of the over current condition. At when the switching current becomes ILIM or more, the overcurrent protection circuit is stopped the MOSFET output. Then at next switching period, the switching operation is returned. The oscillator reduces the NJW1616’s operating frequency when the voltage at the FB pin is low. This frequency foldback helps to control the output current during startup and overload by decreasing minimum ON Duty. 1.245V FB pin Voltage 0V ON SW pin OFF Switching Current ILIM 0 Pulse by Pulse Static Status Frequency Foldback Detect Overcurrent Static Status Fig. 1. Timing Chart at Over Current Detection Thermal Shutdown Function (TSD) When Junction temperature of the NJW1616 exceeds the 175°C*, internal thermal shutdown circuit function stops SW function. When junction temperature decreases to 145°C* or less, SW operation returns with soft start operation. The purpose of this function is to prevent malfunctioning of IC at the high junction temperature. Therefore it is not something that urges positive use. You should make sure to operate within the junction temperature range rated ( 150 C). (* Design value) Standby Function The SHDN pin is used to place the NJW1616 in shutdown, disconnecting the output and reducing the input current to less than 1μA. The NJW1616 stops the operating and becomes standby status when the SHDN pin becomes less than 0.3V or OPEN. You should connect to the VIN pin when you do not use standby function. - 12 - Ver.2016-03-01 NJW1616 Application Manual NJW1616-T Technical Information Application Information Inductors Because a large current flows to the inductor, you should select the inductor with the large current capacity not to saturate. Optimized inductor value is determined by the input voltage and output voltage. The Inductor setting example is shown in Table 2. When increasing inductor value, it is necessary to increasing capacity of an output capacitor and to secure the stability of application. The minimum of inductor value is restricted from the following equation, when ON duty exceeds 50%. VIN L 2 D ON 0.4 1 [ H] Reducing L decreases the size of the inductor. However a peak current increases and adversely affects the efficiency. (Fig.2) Moreover, you should be aware that the output current is limited because it becomes easy to operating to the overcurrent limit. The peak current is decided the following equation.

If the power supply impedance of the power supply circuit is large the input voltage fluctuation occurs. As the result, it will not be possible to take sufficient advantage of the NJW1616 performance. Therefore insert an input capacitor as close to the MOSFET as possible. A ceramic capacitor is the optimal for input capacitor. The effective input current can be expressed by the following equation. IRMS VOUT IOUT VIN VIN VOUT [ A] In the above equation, the maximum current is obtained when VIN = 2 VOUT, and the result in this case is IRMS = IOUT (MAX) 2. When selecting the input capacitor, carry out an evaluation based on the application, and should use a capacitor that has adequate margin. Output Capacitor An output capacitor stores power from the inductor and stabilizes the voltage provided to the output. Because the NJW1616 corresponds to the output capacitor of low ESR the ceramic capacitor is the optimal for compensation. Table.2 shown the output capacitor setting example.

In addition, you should consider varied characteristics of capacitor (a frequency characteristic, a temperature characteristic, a DC bias characteristic and so on) and unevenness peculiar to a capacitor supplier enough. Therefore when selecting a capacitors, you should confirm the characteristics with supplier datasheets. When selecting an output capacitor, you must consider Equivalent Series Resistance (ESR) characteristics, ripple current, and breakdown voltage. If using low ESR type capacitors, it is possible to reduce the ripple voltage. The output ripple noise can be expressed by the following equation. Vripple(p p) ESR IL [ V ] The effective ripple current that flows in a capacitor (Irms) is obtained by the following equation. Irms - 14 - IL 2 3 [ Arms] Ver.2016-03-01 NJW1616 Application Manual NJW1616-T Technical Information Application Information (Continued) Catch Diode When the switch element is in OFF cycle, the stored power in the inductor flows via the catch diode to the output capacitor. Therefore during each cycle the current flows to the diode in response to load current. Because a diode forward saturation voltage and current accumulation are cause of power loss, a Schottky Barrier Diode (SBD), that has a low forward saturation voltage is ideal. An SBD also has a short reverse recovery time. If the reverse recovery time is long, shoot through current flows when the switching transistor transitions from OFF cycle to ON cycle. This current may lower efficiency and affect such factors as noise generation. Setting Output Voltage, Compensation Capacitor The output voltage VOUT is determined by the relative resistances of R1/R2. The current that flows in R1/R2 must be a value that can ignore the bias current that flows in Error AMP. R2 1 R1 VOUT VB [ V ] The zero points are formed by parallel addition CFB to R2, and it can improve the phase compensation of the NJW1616 The zero point is decided the following equation. f Z1 2 1 [Hz] R2 C FB You should set the zero point as a guide from 40kHz to 70kHz.

You should attempt the transition voltage decrease by making a current loop area minimize as much as possible. Therefore, you should make a current flowing line thick and short as much as possible. Fig.3. shows a current loop at step-down converter. Especially, should lay out high priority the loop of CIN-SW-SBD that occurs rapid current change in the switching.

The voltage sensing feedback line should be as far away as possible from the inductance. Because this line has high impedance, it is laid out to avoid the influence noise caused by flux leaked from the inductance. Fig.4 shows example of wiring at buck converter.
