Регуляторы тока светодиодных ламп MAX16828ASA+

Драйвер светодиода , линейный, 1 выход, ШИМ затемнение, 6.5В до 40В вход, 38.6В/200мА выход, NSOIC-8

The MAX16828ASA+ from Maxim Integrated Products is a high voltage 200mA adjustable linear high brightness LED driver with PWM dimming in 8 pin NSOIC package. This current regulator operates from a 6.5V to 40V input voltage range and delivers up to 200mA to high brightness LED (HB LED) loads. The output current is adjusted by using an external current sense resistor in series with the LEDs. The MAX16828's dimming input allows wide range pulsed PWM operation. An on-board pass element minimizes external components while providing ±3.5% output current accuracy. Typical applications include emergency vehicle warning lights, signage and indicators, ambient and architectural lighting, LED bulbs and display backlighting.
