AP3012KTR-G1

Diodes Incorporated · DC-DC Converters · SOT-23-5

AP3012KTR-G1 from Diodes Incorporated, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SW output Switch pin. Collector of the internal 36V/500mA bipolar NPN power switch; connect the boost inductor and Schottky diode here. Output voltage on this node can go up to 29V but must not exceed the 29V OVP threshold or the device enters shutdown.
2 GND power_in Ground pin. Connect directly to the local ground plane; carries the switch return current so a low-impedance connection is important.
3 FB input Feedback pin. Internally compared to a 1.25V reference; connect an R1/R2 resistor divider from VOUT to set the output voltage per VOUT = 1.25V * (1 + R1/R2). FB pin bias current is ~45nA typ.
4 SHDN input Active-low shutdown pin (bar over SHDN in datasheet). Drive to 1.5V or higher to enable the device (ON); drive to 0.4V or lower to disable (OFF). Absolute max 16V; typical pin bias current ~55uA.
5 VIN power_in Input supply pin. Recommended operating range 2.6V to 16V (absolute max 20V). Must be locally bypassed with a ceramic capacitor close to the pin.
