Sillumin Semiconductor Co., Ltd. www.sillumin.com SLM411A Rev. B July 2016 42V 15 ~ 350mA Linear Constant Current LED Driver with PWM Dimming Control GENERAL DESCRIPTION The SLM411A is a wide input range, high precision constant current LED driver which provides costeffective solution for advertising light boxes, landscape lighting and other LED illumination application. For most applications, SLM411A only need one current setting resistor from SET to GND, and one ceramic bypass capacitor from VIN to GND, no aluminum capacitor, Schottky diode or inductor needed. The dimming range will be greater than 1024:1 at 100Hz dimming frequency. PWM frequency can be set between 100Hz~20kHz.
