PMP9126 Reference Design

Texas Instruments

36 to 75VDC Input 5V/15A Active Clamp Forward 1/8 Brick Form Factor Reference Design

Description

This reference design generates a 5V/15A output from a 36V to 75V telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD17501Q5A and CSD18502Q5B: implemented as a synchronous rectifiers: provides for a highly efficient design. This design is laid out in a standard eighth brick footprint and achieves efficiencies up to 94%.  It uses only surface mount components: including ceramic output capacitors.

Features
  • 36V to 75VDC input 5V/15A output 94% efficiency Industry Standard Eighth Brick Footprint Features UCC2897A Controller along with TI NexFET Synchronous Rectifiers Active Clamp Forward Topology Reduced conduction losses and die area of the synchronous rectifiers
Applications
  • Baseband unit (BBU)
  • Active antenna system mMIMO (AAS)
  • Indoor backhaul
  • Macro remote radio unit (RRU)
Product Categories
  • Power management
