AP3064EV1, Evaluation Board based on AP3064 High Efficiency Boost Controller
参考設計 著者: Diodes Incorporated
AP3064EV1, Evaluation Board utilizes the AP3064 high efficiency boost controller with 4-string current sources for driving WLED backlight. The AP3064 operates over a wide input voltage range from 4.5V to 33V. The current of 4 strings are simply programmed from 20mA to 220mA with an external resistor. The current matching between each string is 1.5% (Type). Its operating frequency can be adjusted from 0.1MHz to 1MHz, which allows trade-offs between external component size and system efficiency. The AP3064 supports external Pulse Width Modulation (PWM) Dimming Control with a wide dimming frequency range from 100Hz to 20kHz
