DIO8241JST3 from DIOO, in a SOT-23. 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, where the capacitor to GND sets the final amplitude of the current ripple; absolute maximum -0.3 to 6 V. |
| 2 | GND | power_in | Power ground. |
| 3 | LEDN | passive | Connects to the cathode of the LED string (drain of the internal 100 V NMOSFET); absolute maximum 100 V. |
