RT8295BHZSP from Richtek Tech, in a SOP-8-EP. 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 | BOOT | passive | Bootstrap for the high-side gate driver; connect a 0.1μF or greater ceramic capacitor from BOOT to SW. |
| 2 | VIN | power_in | Input supply voltage, 4.5V to 23V; must be bypassed with a suitably large ceramic capacitor. |
| 3 | SW | output | Switch node; connect this pin to an external L-C filter. |
| 4 | GND | power_in | Ground; the exposed pad must be soldered to a large PCB and connected to GND for maximum power dissipation. |
| 5 | FB | input | Feedback input connected to the converter output, regulating to the internal 0.8V typical reference through an internal divider or an external resistive divider for adjustable output. |
| 6 | COMP | passive | Compensation node for the control loop; connect a series RC network from COMP to GND, with an additional capacitor from COMP to GND sometimes required. |
| 7 | EN | input | Chip enable, active high; a logic-low (<0.4V) forces shutdown with supply current below 3μA, and a 100kΩ pull-up from VIN gives automatic startup. |
| 8 | SS | passive | Soft-start control; a capacitor from SS to GND sets the soft-start period, with 0.1μF giving 13.5ms typical. |
| 9 | GND | power_in | Exposed thermal pad on the package bottom, which must be soldered to a large PCB copper area and connected to GND for maximum power dissipation. |
