AW99703
Dec. 2019 V1.2
High Efficiency, 3-Channel WLED Driver with Flash Function
Feature
General Description
±1% current matching across voltage,
AW99703 is a highly accurate, highly matching
temperature, and process
three-string LCD backlighting power solution. It is a
±3% current accuracy across voltage,
temperature, and process
High efficiency, up to 91%
Up to 29.6mA/string in backlight mode and up to
79.9mA/string in flash mode
I2C/PWM dual dimming control mode
11-bit I2C exponential or linear mapping with
programmable transition ramp time
Programmable current sink turn on/off ramp
time
Selectable boost converter switching frequency
1MHz or 500kHz with shift up and down option
l highly integrated step-up DC-DC converter
operating with a wide input voltage from 2.7V to
5.5V and a temperature range from -40°C to 85°C,
accommodating 1-cell lithium ion battery or 5V
ia supply.
t The AW99703 integrates a high voltage MOSFET,
and three high accuracy, high voltage current sinks.
n Each current sink can be regulated up to 29.6mA in
backlight mode. In flash mode, flash current sink
e can be regulated up to 79.9mA, and flash timeout
can be regulated up to 1.5sec.
d The LED current is adjusted via an I2C interface or
fi through a logic level PWM input. The PWM duty
Programmable slew rate control minimize
switching noise and improve EMI performance
ncycle is internally sensed and mapped to an 11-bit
linear current.
o Five configurable OVP thresholds (17.5V, 24V,
31V, 38V, 41.5V)
Thorough protection features include LED fault
(open and short) protection, cycle-by-cycle current-
C Four configurable current limit thresholds
(900mA,1800mA, 2700mA, 3400mA)
limit protection, output over-voltage protection and
thermal shutdown.
ic Programmable flash current and timeout
LED open/short protection
