AL3065AS16-13

NOT RECOMMENDED FOR NEW DESIGN CONTACT US AL3065A BOOST CONTROLLER WITH 4-CHANNEL HIGH PERCISION CURRENT SOURCE Description Pin Assignments 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. (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. Robust protection features include cycle-by-cycle current limit, softstart, UVLO, programmable OVP, OTP, open/short LED protection, Schottky diode short and open protection, inductor short-circuit protection, and VOUT short protection. SO-16 The IC is available in SO-16 packages.
