May 2018 V1.3
600mA PWM Configurable Front Flash LED Driver
FEATURES
GENERAL DESCRIPTION
Front Flash LED Driving 600mA Maximum Flash Current PWM Dimming Input Flash Timeout Protection: 1.2s LED Current Accuracy: ±8% Low Dropout Voltage: 140mV@600mA (Typ.) Efficiency: 94% (VIN=3.6V, VF=3.4V) LED Short Protection
The AW36406 is a low voltage-drop current sink
l LED driver, which supports both flash and torch
modes. The current-regulation sink integrated in the chip makes the LED current be capable of
a keeping constant when input voltage, LED forward i voltage or temperature are changing. The LED t current can be adjusted by PWM signal into the
EN pin, and the maximum value is 600mA.
n The AW36406 is available in an ultra-small
1.5mm× 1.5mm×0.55mm DFN-8 package.
