# RT8096AHGJ5

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

RT8096AHGJ5 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: a logic-high enables the converter and a logic-low forces shutdown mode, with VIH at least 1.5V and VIL at most 0.4V. |
| 2 | GND | power_in | Power ground. |
| 3 | LX | output | Switch node of the synchronous buck converter, connected to the inductor. |
| 4 | VIN | power_in | Supply voltage input; the RT8096A 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 typical reference. |
