MLX81150
LIN-Slave for relay and DC motor control
4.4 LED-Lamp driver, switch mode power supply
In this application the MLX81150 drives a LED lamp with several high power LEDs in a DC-DC converter
configuration. The module itself is controlled via the LIN bus. The current in the LED is regulated to a given
value. Adjusting PWM frequency and PWM ratio allow to control the transformator in a very efficient way
from EMC perspective as well as from energy point of view.
