HX1509D-ADJRG from HANSCHIP semiconductor, 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 pin; the HX1509 operates from 4.5V to 42V DC, and Vin should be bypassed to GND with a suitably large capacitor to eliminate input noise. |
| 2 | OUTPUT | output | Power switch output pin (SW) is the switch node that supplies power to the output. |
| 3 | FEEDBACK | input | Feedback pin (FB) senses the output voltage through an external resistor divider and regulates it, with a feedback threshold voltage of 1.23V. |
| 4 | ON/OFF | input | Enable pin: drive low to turn the device on and drive high to turn it off, and it defaults to low when floating. |
| 5 | GND | power_in | Ground pin that must be laid out carefully, placed outside the Schottky diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into the HX1509. |
| 6 | GND | power_in | Ground pin that must be laid out carefully, placed outside the Schottky diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into the HX1509. |
| 7 | GND | power_in | Ground pin that must be laid out carefully, placed outside the Schottky diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into the HX1509. |
| 8 | GND | power_in | Ground pin that must be laid out carefully, placed outside the Schottky diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into the HX1509. |
