AP3612中文资料led-drivers-for-displays-backlights数据手册Diodes规格书

描述 Description

The AP3612 is a high efficiency boost controller with 12-string current sources for driving W°C backlight. It operates over a wide input voltage range from 4.5V to 33V.

The current of 12 strings are simply programmed from 20mA to 75mA 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 AP3612 features Cycle-by-cycle Current Limit, Soft Start, Under Voltage Lock Out (UVLO) protection, programmable OVP, Over Temperature Protection (OTP), open/short °C protection, VOUT short protection and Schottky diode short-circuit protection.

简介

AP3612属于集成电路（IC）的LED驱动器。由制造生产的AP3612LED 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。
