• AL3065EV1, Evaluation Board utilizes the AL3065 high efficiency boost controller with 4-string current sources for driving WLED backlight. The AL3065 operates over a wide input voltage range from 4.5 to 33V. The current of 4 strings are simply programmed from 20mA to 400mA with an external resistor. The current matching between each string is 1.5% (Type). Its operating frequency can be adjusted from 0.1 to 1MHz, which allows trade-offs between external component size and system efficiency. The AL3065 supports three dimming modes: direct PWM dimming, PWM to analog dimming and DC to analog dimming
