描述 Description

The AP3602A/B are regulated step-up DC/DC converters based on charge pump technique. These ICs have the ability to supply 100mA constant output current or 250mA peak output current for 100ms from 3.0V to 5V input (2.7V to 4.5 V for AP3602B), so they can be used as white °Cs driver or flash °C driver.

The AP3602A/B have very low power dissipation and high efficiency in typical applications. Other features include over-temperature protection, low temperature coefficient and etc. to meet some special requirements of hand-held battery powered devices.

Only 3 external capacitors are required in applications, which helps to save space and lower cost. These chips also have a disable terminal to turn on or turn off the chip to ease the use.

简介

AP3602B属于集成电路（IC）的LED驱动器。由制造生产的AP3602BLED 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。
