Diodes Incorporated · LED Drivers · TSOT-23-5
AP8803WTG-7 from Diodes Incorporated, in a TSOT-23-5. 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 | SW | output | Switch pin that connects to the inductor/freewheeling diode; keep track length short at this pin to reduce EMI, with a switch voltage rating of -0.3 to +30V (40V transient) and 1.25A maximum switch current. |
| 2 | GND | power_in | Ground pin. |
| 3 | CTRL | input | Dimming and on/off control input: leave floating for normal operation (VREF = 1.25V), drive below 0.2V to turn off the output and enter low-current standby, or drive with 0.3V to 1.25V DC (or a PWM signal) to adjust the output current from 25% to 100% of nominal. |
| 4 | SET | input | Set nominal output current pin, where an external resistor RSET connected between VIN and SET sets the nominal LED current as 0.1V/RSET. |
| 5 | VIN | power_in | Input supply pin for 8V to 30V operation, which must be locally decoupled to GND with a >2.2µF X7R ceramic capacitor. |
