描述 Description

The AP3041 is a current mode high voltage low-side channel MOSFET controller, which is ideal for boost regulators. It contains all the features needed to implement single-ended primary topology DC/DC converters.

The input voltage of AP3041 ranges from 5V to 27V. Its operation frequency is adjustable from 100kHz to 1MHz.

The AP3041 has UVLO (Under Voltage Lock Out) circuit. It uses two external resistors to set the UVLO voltage. The AP3041 also has an over output voltage protection to limit the output voltage. The OVP voltage can be set through external resistors. If the output voltage is higher than the OVP high threshold point, it will disable the driver and the system is latched up. The output short circuit protection as well as °C low side short to ground detection function can be applied in system.

The AP3041 has other protection functions, such as °C short protection, °C high side short to ground protection, diode short protection, over current protection, over temperature protection and so on.

简介

AP3041属于集成电路（IC）的LED驱动器。由制造生产的AP3041LED 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。
