RT8097AHGB

Richtek Tech · DC-DC Converters · SOT-23-5

RT8097AHGB from Richtek Tech, in a SOT-23-5. 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 EN input Enable control input: logic-high (VIH min 1.5V) enables the converter and logic-low (VIL max 0.4V) forces shutdown.
2 GND power_in Power ground.
3 LX output Switch node, driving the inductor from the internal high-side and low-side power MOSFETs.
4 VIN power_in Supply voltage input; the RT8097A operates from a 2.7V to 6V input.
5 FB input Feedback voltage input; an external resistor divider from the output to GND sets the output voltage against the 0.6V (typ.) reference.
