MSL2042 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.
MSL2042 Key Features
- Drives Four Parallel High Power LED Strings
- Greater than 1A LED String Current with External N-Channel MOSFETS
- Operates Stand-Alone with PWM Input(s) Controlled Dimming
- Four PWM Inputs Allow Individual Frequency, Brightness and Phase Control of each LED String (MSL2041)
- One PWM Input Controls the Frequency and Brightness of the Automatically Phase Shifted Strings (MSL2042)
- 8-bit Adaptive Optimization of String Power Supply for Maximum Efficiency
- Multiple MSL2041/2s Share a String Supply and Automatically Negotiate the Optimum Supply Voltage
- ±0.5% Current Matching Between Strings
- String Open-Circuit and LED Short-Circuit Fault Detection and Protection
- External MOSFETs Offer Flexibility of LEDs Used in Each String for high current and/or voltage
