描述 Description

The AP3064 is a high efficiency boost controller with 4-string current sources for driving W°C backlight. It 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% (Typ). Its operating frequency can be adjusted from 0.1MHz to 1MHz.

The AP3064 features cycle-by-cycle current limit, soft-start, under voltage lockout (UVLO) protection, programmable OVP, over temperature protection (OTP), open/short °C protection, VOUT short/Schottky diode open protection

简介

AP3064属于集成电路（IC）的LED驱动器。由制造生产的AP3064LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
