AP1509-5.0M

HGSEMI · DC-DC Converters · SOP-8

AP1509-5.0M from HGSEMI, in a SOP-8. 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 Supply voltage input operating from 4.5V to 42V DC; bypass Vin to GND with a suitably large capacitor to eliminate input noise.
2 OUTPUT output Power switch output (SW) node, the switch node that supplies power to the output.
3 FEEDBACK input Feedback input (FB) senses the output voltage through an external resistor divider and regulates it to a 1.23V feedback threshold.
4 ON/OFF input Enable pin: drive low to turn the device on and high to turn it off; floating defaults low.
5 GND power_in Ground pin; layout must place it outside the Schottky diode to output capacitor ground path so switching current spikes do not induce voltage noise into the IC.
6 GND power_in Ground pin; layout must place it outside the Schottky diode to output capacitor ground path so switching current spikes do not induce voltage noise into the IC.
7 GND power_in Ground pin; layout must place it outside the Schottky diode to output capacitor ground path so switching current spikes do not induce voltage noise into the IC.
8 GND power_in Ground pin; layout must place it outside the Schottky diode to output capacitor ground path so switching current spikes do not induce voltage noise into the IC.
