描述 Description

The AP3032 is an inductor-based DC/DC boost converter designed to drive up to 4 rows of °Cs with 7 series for each in parallel for backlight.

A constant frequency 1MHz PWM control scheme is employed in this IC, which means tiny external components can be used. Specifically, 1mm tall 6.8μH inductor and 1μF aluminum output capacitor for the typical application is sufficient.

The over output voltage protection is equipped in AP3032, which protects the IC under open load condition. The AP3032 includes UVLO, soft-start, stand-by mode, current limiting and OTSD to protect the circuit under over load condition.

简介

AP3032属于集成电路（IC）的LED驱动器。由制造生产的AP3032LED 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。
