Overview

AL3069 FOUR-CHANNEL CURRENT SOURCE BOOST LED DRIVER Description The AL3069 is a high-efficiency four-channel boost controller for WLED backlight applications.
It operates over a wide input voltage range, from 4.
5V to 60V.
The current of the four channels is simply programmed from 20mA to 400mA with an external resistor.
The current match between any channels is ±0.
5% (typical).
Its operating frequency can be adjusted from 0.
1MHz to 1MHz.
The AL3069 can support two independent dimming modes: direct PWM dimming and PWM to analog dimming.
This function makes AL3069 flexible to design in different dimming applications.
Robust protection features include cycle by cycle current limit, softstart, ...
