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.

Design considerations

  • Digital controlled adaptive non-glare
  • Individually dimmable LED Control
  • Accurate LED current control
  • Compact design
  • High efficiency driver design
  • Low EMI solution using small scale highly integrated package technology

Automotive relay replacement - Reliability meets space savings

A relay is often perceived as the ideal device with perfect input/output isolation. Unfortunately, this is not the case. MOSFETs are rapidly becoming the option of choice offer reliability and space savings.
