Description
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 In.
The MSL2041 and MSL2042 compact, high-power LED controllers use external current control MOSFETs to sink up to 1A per string, with string current matc.
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
Applications
* General and architectural lamps
* Street-Lighting
* Post-Regulated or Offline Powered LED Strings
* High CRI LED fixtures
* Down lights and recessed lights
* LCD-TVs
* PC Monitors
* Industrial Displays
* PAR lamps
