MSL2041 Simple 4-string LED Drivers

The MSL2041 and MSL2042 compact, high-power LED controllers use external current control MOSFETs to sink up to 1A per string, with string current matching of ±0.5%. The MSL2041/2 drive four parallel strings of LEDs with fault detection and management of open circuit and short circuit LEDs. The MSL20.

MSL2041 Features

* four PWM inputs that allow independent frequency, dimming and phasing of each string. The MSL2042 has a single PWM input for frequency and dimming control of all four strings, and automatically phase shifts the string drive signals. An external current sense resistor for each string sets full-scale
