# TP8308

**TPOWER** · LED Drivers · SOT-23-6

TP8308 from TPOWER, in a SOT-23-6. 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 | VDD | power_in | Supply input with an internal 5.6 V zener clamp; the absolute maximum VDD-to-GND rating is -0.3 to +6 V, and a dropping resistor is required when the input voltage exceeds 5.6 V. |
| 2 | SW | output | Drain of the internal power MOSFET, rated for -0.3 to +100 V to GND and a power-switch output current of 1.0 A absolute maximum. |
| 3 | MODE | input | High/low brightness mode input (high = 100% output, low = 30% output), absolute maximum -0.3 to +7 V; it must not be left floating and must be tied to VDD or GND when unused, and a 100 nF filter capacitor to GND is required in dimming applications. |
| 4 | GND | power_in | Chip ground. |
| 5 | CS | input | Output current sense pin; the LED average-current sense resistor is connected between CS and GND, with an absolute maximum CS-to-GND rating of -0.3 to +6 V. |
| 6 | NC | unconnected | No connection. |

## CAD (KiCad official)

- Symbol: `TP8308`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `tp8308-etched.step` / `tp8308-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tp8308.step` / `tp8308.glb` are the bare package body.
