MSL2042 Datasheet | Atmel

Atmel LED Drivers MSL2041/MSL2042 Low-Cost, Simple 4-String LED Drivers with External Current Sink MOSFETs, 5000:1 Dimming Range and Per String PWM Input Preliminary Datasheet Description The MSL2041 and MSL2042 pact, 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 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...
