MSL2042 - Simple 4-string LED Drivers

Download the MSL2042 datasheet PDF. This datasheet also covers the MSL2041 variant, as both devices belong to the same simple 4-string led drivers family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
