Description
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%.
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 LED current and is adjustable for all strings equally with an internal 8-bit DAC. The MSL2041/2 adaptively control up to two DC-DC or off-line converters that power the LEDs using Atmel's proprietary.
