Automotive Power Supply with Pre-Boost Reference Design


Design files


The PMP10223 automotive power reference design provides 5.0V @ 1.1A, 3.3V @ 0.6A and 1.3V at 1.0A. A pre-boost provides 9.0V @ 1.7A to ensure proper operation even during startup of the engine. A synchronous buck converters generates 6.0V @ 2.2A as an intermediate rail for the following buck converters.

  • Complete Automotive Power Solution
  • Includes Pre-Boost for Cranking
  • High Efficiency
  • Small Form Factor
