MSL2042 Product details

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%.

The MSL2041/2 drive four parallel strings of LEDs with fault detection and management of open circuit and short circuit LEDs.

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.
