RT7285CGJ6

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

RT7285CGJ6 from Richtek Tech, in a TSOT-23-6L. 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 power_out Bootstrap supply for the high-side gate driver; connect a 0.1µF ceramic capacitor between BOOT and SW.
2 GND power_in Power ground.
3 FB input Feedback voltage input used to set the output voltage through a resistive divider; the converter regulates VFB to 0.6V.
4 EN input Enable control input: logic-high enables the IC and logic-low disables it; do not leave this high-impedance input unconnected.
5 VIN power_in Power input with a range of 4.3V to 18V; must be bypassed with a suitable large ceramic capacitor at this pin.
6 SW output Switch node; connect to the external L-C filter.
