AP63301WU-7

Diodes Incorporated · DC-DC Converters · TSOT-23-6

AP63301WU-7 from Diodes Incorporated, in a TSOT-23-6. 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 FB input Feedback sensing terminal for the output voltage; connect it to the output resistive divider, which references the internal 0.8V reference (absolute maximum -0.3V to +6.0V).
2 EN input Enable input that turns the regulator on when driven high and off when driven low, with a 1.18V precision threshold for UVLO programming; connect to VIN or leave floating for automatic startup (absolute maximum -0.3V to +35.0V).
3 VIN power_in Power input that supplies the IC and the step-down power MOSFETs; drive with a 3.8V to 32V source and bypass to GND with a suitably large capacitor.
4 GND power_in Power ground.
5 SW output Power switching output node that supplies power to the output; connect the output LC filter from SW to the load (DC absolute maximum -0.3V to VIN + 0.3V).
6 BST power_in High-side gate drive boost input supplying the high-side N-channel MOSFET driver; a 100nF ceramic capacitor is recommended from BST to SW.
