2 / 11 page  Data Sheet 340kHz, 3A Synchronous DC-DC Buck Converter AP3503 May. 2012 Rev. 1. 7 BCD Semiconductor Manufacturing Limited 2 Pin Configuration MP Package (PSOP-8) 1 2 3 4 8 7 6 5 Figure 2. Pin Configuration of AP3503 (Top View) Pin Description Pin Number Pin Name Function 1 BS Bootstrap pin. A bootstrap capacitor is connected between the BS pin and SW pin. The voltage across the bootstrap capacitor drives the internal high-side power MOSFET 2 IN Supply power input pin. A capacitor should be connected between the IN pin and GND pin to keep the input voltage constant 3 SW Power switch output pin. This pin is connected to the inductor and bootstrap capacitor 4 GND Ground pin 5 FB Feedback pin. This pin is connected to an external resistor divider to program the system output voltage. When the FB pin voltage exceeds 1.1V, the over voltage protection is triggered. When the FB pin voltage is below 0.3V, the oscillator frequency is lowered to realize short circuit protection 6 COMP Compensation pin. This pin is the output of the transconductance error amplifier and the input to the current comparator. It is used to compensate the control loop. Connect a series RC network from this pin to GND. In some cases, an additional capacitor from this pin to GND pin is required 7 EN Control input pin. EN is a digital input that turns the regulator on or off. Drive EN high/low to turn on/off the regulator. Pull up with 100k Ω resistor for automatic startup 8 SS Soft-start control input pin. SS controls the soft-start period. Connect a capacitor from SS to GND to set the soft-start period. A 0.1 µF capacitor sets the soft-start period to 15ms. To disable the soft-start feature, leave SS unconnected EP Exposed pad. It should be connected to GND in PCB layout |
