AW9968DNR

AWINIC(Shanghai Awinic Tech) · LED Drivers · DFN-6-EP(2x2)

AW9968DNR from AWINIC(Shanghai Awinic Tech), in a DFN-6-EP(2x2). 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 FB input Feedback pin: RSET is connected from FB to GND, and the loop regulates FB to a 200mV typical reference in backlight mode.
2 STROBE input Strobe signal input that synchronizes the flash pulse to image capture; the AW9968 exits flash mode if STROBE stays high for more than 350ms.
3 GND power_in Ground.
4 SW output Switching node of the boost converter; the open-LED overvoltage threshold is measured on this pin, 38V typical with a 36V to 40V range.
5 CTRL input Enable pin that also accepts PWM digital dimming; a logic low for more than 2.5ms shuts the driver down.
6 VIN power_in Power input with an input voltage range of 2.7V to 5.5V.
7 GND power_in Exposed pad that should be soldered to the PCB and connected to GND.
