AL1665S-13

Diodes Incorporated · LED Drivers · SOP-8

AL1665S-13 from Diodes Incorporated, in a SOP-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 ADIM input Analog dimming input that accepts a 50mV to 2.5V DC signal, giving a 5% to 100% dimming range.
2 NTC/PWM input NTC input for thermal foldback and PWM dimming input, where logic high must be above 1V and logic low below 0.5V for a 0.5% to 100% range at 1kHz.
3 COMP passive Loop compensation pin with an absolute maximum voltage of -0.3 to 7 V, where a 1µF to 2µF CCOMP is recommended and the pre-charge voltage is set by RCOMP.
4 CS input Current sense pin to be connected to the source of the primary switch, rated -0.3 to 7 V, with the primary current clamp at 2 V.
5 GND power_in Ground reference for the device, to which all voltages are measured.
6 OUT output Gate driver output with a driver output voltage rating of -0.3 to 20 V.
7 VCC power_in Supply voltage for the gate driver and control circuits, with an operating range of 8.5 V to VCC_OVP (min) and an absolute maximum of 30 V.
8 FB input Feedback voltage sensing input from the auxiliary winding, rated -0.3 to 7 V.
