资 源 简 介

A703 is a high voltage, adjustable constant currentdriver for LED applicaTIons. Two regulated current ports aredesigned to provide uniform and pure DC constant currentsinks for driving LEDs within a large range VF variaTIons.A703 provides users 2-channel constant current portsto match LEDs with equal current. Users may adjust theoutput current from 20mA to 150mA through an externalresistor, RSET, which gives users flexibility in controlling thelight intensity of LEDs. It also could adjust LED brightnessfrom 0% to 100% via enable pin (EN) with Pulse WidthModulaTIon signal.The thermal protecTIon function protects IC from overtemperature (150°C). Also, the thermal pad enhances the package power dissipation.
