Adaptive Front LED lights

Front LED lighting is the most power-hungry lighting application and often has a high degree of complexity. A multi-channel boost/buck topology is often preferred as this provides flexibility for the LED drive. The output LEDs can be dimmed by using a combination of low-power bipolar transistors with a shift register.
