Overview

PMP9750 is a CLL resonant converter reference design with 400VDC input and 28V/9A ouput. Unlike LLC series resonant converter, CLL resonant converter used in PMP9750 utilizes its output inductor to minimize the size of the resonant tank. With resonant controller UCC25600 and bridge driver UCC27714, PMP9750 is able to achieve 95.7% peak efficiency.

Features
  • 400VDC input to 28V/9A output
  • Utilize compact, high efficieny CLL resonant converter
  • Test data included
  • Board dimension: W x L x H = 2.05" x 3.8" x 1.21"
  • Achieve 95.7% peak efficiency
