Description

The PMP20054 converts a 5 V input to a 0.85 V output @ 40 A (2 Phase) using the TPS40322. The output capacitors are all ceramic for a cost effective and small solution.

Features
  • Low Vin design
  • High power dual phase output
  • All ceramic capacitors on input/output
  • Small solution size
