High Current LED Driver This device is designed to replace discrete solutions for driving LEDs in low voltage AC-DC applications 5.0 V, 12 V or 24 V. An external resistor allows the circuit designer to set the drive current for different LED arrays. This discrete integration technology eliminates individual components by combining them into a single package, which results in a significant reduction of both system cost and board space. The device is a small surface mount package (SO-8). Features • Supplies Constant LED Current for Varying Input Voltages • External Resistor Allows Designer to Set Current - up to 500 mA • Offered in Surface Mount Package Technology (SO-8) • Pb-Free Package is Available
Наличие высокого напряжения на присоске можно проверить отверткой, соединенной с корпусом через резистор 3-5 МОм Наличие резистора обязательно, так как без него из-за большого тока можно повредить умножитель или строчный трансформатор типа ТДКС.
