• AL3066EV1, Evaluation Board for the AL3066 is a high efficiency 4-channel boost controller for WLED backlight applications. It operates over a wide input voltage ranged from 4.5V to 33V. The current of the 4 channels is simply programmed from 20mA to 400mA with an external resistor. The current match between any channel is ±1.5% (typical). Its operating frequency can be adjusted from 0.1MHz to 1MHz. The AL3066 can support two dimming modes: direct PWM dimming, PWM to analog dimming
