DIO8242CTC3 from DIOO, in a SOT-89-3. 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 | VC | passive | LED current ripple programming pin; the capacitor CC between VC and GND sets the final ripple amplitude, and VC is rated -0.3 to 6 V. |
| 2 | LEDN | passive | Connects to the cathode of the LED string (drain of the internal NMOSFET), with an absolute maximum rating of 100 V and recommended operation below 100 V. |
| 3 | GND | power_in | Power ground; the sensing resistor Rcs is connected between the NMOSFET source and GND. |
