RT6212BHRGJ6F

Richtek Tech · DC-DC Converters · TSOT-23-6

RT6212BHRGJ6F from Richtek Tech, in a TSOT-23-6. 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 GND power_in System ground provides the ground return path for the control circuitry and the low-side power MOSFET.
2 LX output Switch node supplies power to the output and connects the output LC filter from LX to the output load.
3 VIN power_in Power input supplies the power switches of the device, which operate from a 4.5V to 18V supply range.
4 FB input Feedback voltage input sets the desired output voltage through an external resistive divider, with the feedback voltage typically 0.765V or 0.8V.
5 EN input Enable control input: floating this pin or connecting it to GND disables the device, and connecting it to logic high enables the device.
6 BOOT power_out Bootstrap supply for the high-side gate driver, where a 100nF or greater capacitor should be connected from LX to BOOT.
