AP63300QWU-7

Diodes Incorporated · DC-DC Converters · TSOT-26

AP63300QWU-7 from Diodes Incorporated, in a TSOT-26. 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 to the resistive divider of the output (0.8V reference).
2 EN input Enable input that turns the regulator on when high and off when low; connect to VIN or leave floating for automatic startup, with a precision threshold of 1.18V for adjusting the UVLO.
3 VIN power_in Power input supplying the IC and the 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 power_out Power switching output node that supplies power to the output; connect the output LC filter from SW to the load.
6 BST passive High-side gate drive boost input supplying the high-side N-channel MOSFET driver; a 100nF capacitor is recommended from BST to SW.
