Richtek Tech · DC-DC Converters · SOT-23-5
RT8008GB 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 | Chip enable, active high: do not leave EN floating, and keep VEN below VIN + 0.6V. |
| 2 | GND | power_in | Ground; pin 2 is also the case reference used for the junction-to-case thermal resistance (θJC) measurement. |
| 3 | LX | output | Switching pin with high-frequency voltage swing, which should be kept small in area and away from analog components. |
| 4 | VIN | power_in | Power input with a 2.5V to 5.5V supply range, with the input capacitor CIN placed within 2mm of VIN. |
| 5 | FB/VOUT | input | Feedback input that senses a fraction of the output through the resistive divider (VREF 0.6V typ.) for adjustable versions, and is labeled VOUT in the fixed-voltage application circuit. |
