AW36406
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. And
e only one multi-layer ceramic capacitor is needed
Under Voltage Lock Out (UVLO)
Over Thermal Protection(OTP)
Ultra Small 1.5mm×1.5mm DFN-8 Package
Compatible with AW36404
fid for the peripheral of the solution.
In shut down mode, the AW36406 turns off all
internal circuit and the consumption is less than
1μA.
APPLICATIONS
nThe device requires 2.7V~5.5V input voltage
range and an operating temperature range of -40
o~ 85.
