AP63357DV-7

Diodes Incorporated · Power Management ICs · VDFN3020-13

AP63357DV-7 from Diodes Incorporated, in a VDFN3020-13. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power input that supplies the IC and the step-down power MOSFETs, to be driven from a 3.8V to 32V source and bypassed to GND with a suitably large capacitor.
2 EN input Digital enable input that turns the regulator on when driven high and off when driven low, with a precision threshold of 1.18V for programming UVLO.
3 FB input Feedback sensing input for the output voltage, connected to the output resistive divider with a 0.8V reference.
4 COMP passive Compensation pin, connected to GND to use internal loop compensation or to an external RC network to adjust the loop response.
5 PG output Open-drain power-good output with an internal 5MΩ pull-up resistor, pulled to GND when the output is outside its regulation limits or during soft-start.
6 BST power_in High-side gate drive boost input that supplies the high-side N-channel MOSFET drive, with a 100nF capacitor recommended from BST to SW.
7 NC unconnected No internal connection; the pin can be tied to any other pin or left floating.
8 GND power_in Power ground.
9 SW power_out Power switching output node that supplies power to the output, with the output LC filter connected from SW to the output load.
