Pre-regulator reference design for automotive LED headlamp drivers(PMP30352)

This pre-regulator reference design delivers up to 45 W output power for automotive LED headlamp drivers. For the nominal input voltage range of 9.0 V to 16.0 V, the design delivers an output voltage of 45.0V with a maximum load current of 1.0 A. The power supply is operational for an input voltage range between 5.0 V and 24.0 V. An optional external dithering function is also available.


  • High efficiency for low power dissipation in space constrained applications
  • Smallest possible footprint for single-side placement in space constrained applications
  • Good load transient behavior resulting in small output voltage deviation
  • Optional external dithering functionality
