DIO8242HST3 from DIOO, in a SOT-23-3. 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 | input | LED current ripple programming pin; the integrating capacitor CC between VC and GND sets the ripple-removal amplitude, and the absolute maximum rating is -0.3 to 6 V. |
| 2 | GND | power_in | Power ground reference for the device, with the NMOSFET source sense resistor Rcs connected between the source and GND. |
| 3 | LEDN | passive | Connects to the cathode of the LED string (drain of the internal NMOSFET), with an absolute maximum rating of 100 V. |
