AL3069规格书详情
描述 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, soft-start, UVLO, programmable OVP, OTP, open/short LED protection, Schottky diode short and open protection, inductor short-circuit protection and VOUT short protection.
The IC is available in SO-16 package.
