AP61302QZ6-7

Diodes Incorporated · DC-DC Converters · SOT-563

AP61302QZ6-7 from Diodes Incorporated, in a SOT-563. 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, connected to the resistive divider of the output (0.6V reference, VFB abs max -0.3 to VIN + 0.3V).
2	GND	power_in	Power ground.
3	VIN	power_in	Power input supplying the IC and the power MOSFETs, driven with a 2.4V to 5.5V source and bypassed to GND with a suitably large capacitor.
4	SW	output	Power switching output node that supplies power to the output through the LC filter (abs max -1.0 to VIN + 0.3V DC).
5	EN	input	Enable input that turns the regulator on (high) or off (low) and programs the operation mode (PFM or PWM); logic high threshold 0.91V typ, low threshold 0.83V typ.
6	PG	output	Open-drain power-good output pulled to GND when the output voltage is out of regulation limits or during soft-start, with internal 5MΩ pull-up to VIN (abs max -0.3 to +6.0V).
