# RT8096BHGJ5

**Richtek Tech** · DC-DC Converters · TSOT-23-5

RT8096BHGJ5 from Richtek Tech, in a TSOT-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 for the converter. |
| 3 | LX | power_out | Switch node; LX voltage is rated from -0.3V to (VIN + 0.3V) per the absolute maximum ratings. |
| 4 | VIN | power_in | Supply voltage input; the RT8096B operates from a 2.5V to 6V input. |
| 5 | FB | input | Feedback voltage input; an external resistor divider from the output to GND, tapped at FB, sets the output voltage against the 0.6V (typ) reference. |
