Jan 2019 V1.4
High Efficiency, Support 0.3% PWM Dimming Boost WLED Driver
FEATURES
GENERAL DESCRIPTION
Support 0.3% PWM dimming
The AW9967 is a white LED (WLED) driver with
l
200mV Reference Voltage Up to 89% Efficiency for 2P7S LEDs PWM control input for CABC operation 1.1MHz Switching Frequency 38V Over-voltage Protection for up to 10 LEDs
in Series 2.7V to 5.5V Input Voltage Range
tia integrated boost converter. The boost converter
runs at 1.1MHz fixed switching frequency, with an internal 40V, 2A switch FET, the AW9967 can drive one string (up to 10 LEDs) and parallel LED strings.
n The full-scale WLED current can be set by the
equation 200mV/RSET. RSET should be changed for
e parallel applications.
