NEW PRODUCT AL3065A BOOST CONTROLLER WITH 4-CHANNEL HIGH PERCISION CURRENT SOURCE Description The AL3065A is a high level integration boost controller with four channels for WLED backlight applications. It operates over a wide input voltage ranging from 4.5V to 33V. Pin Assignments (Top View) 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 AL3065A can be dimmed by one of the following modes: direct PWM dimming, PWM-to-analog dimming, or DC-to-analog dimming.
