DIO8242F2TC3 from DIOO, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VC | input | LED current ripple programming pin; an external capacitor CC placed between VC and GND acts as an integrating capacitor that sets the final amplitude of the LED current ripple; pin voltage range -0.3 to 6 V. |
| 2 | LEDN | passive | Drain of the internal 100 V NMOSFET; connects directly to the cathode of the LED string to sink and regulate the LED current; maximum input voltage 100 V, maximum current 120 mA, MOSFET RDS(on) 8 Ω. |
| 3 | GND | power_in | Power ground reference; a sensing resistor Rcs is connected between the MOSFET source and this pin to support current regulation. |
