RT8295BHZSP

Richtek Tech · DC-DC Converters · SOP-8-EP

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.
