**Diodes Incorporated** · LED Drivers · SO-8

AL8823S-13 from Diodes Incorporated, in a SO-8. 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 | CS | input | Input current sense pin, with boost sense voltage low level of -90 mV typical at VCOMP = 0V. |
| 2 | FB | input | LED output current feedback pin; the RFB resistor from FB to ground sets the LED current, with FB pin voltage specified from 215 mV to 229 mV. |
| 3 | COMP | passive | Control loop compensation pin, where a 1µF ceramic capacitor to ground stabilizes the loop and VCOMP ranges from 0V to 5V. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | VIN | power_in | IC input voltage pin, supplied from the boost output voltage, with a recommended operating range of 5V to 36V and internal OVP that turns off the switch above 39V. |
| 6 | VCC | power_out | Internal regulator output for the device supply, typically 5V, which requires a 10V rated ceramic capacitor (4.7µF is adequate for many applications) and limits external loads to less than 8mA. |
| 7 | OUT | output | Gate driver output for the external MOS switch, with VOH of 4.5V minimum and VOL of 0.4V maximum. |
| 8 | NC | unconnected | Not connected internally. |
