Description

The purpose of the UCC28056BEVM-296 (EVM) is to aid in evaluation of the UCC28056X transition mode boost PFC converter. The EVM is a stand-alone PFC converter designed to operate with 85 to 265 VRMS, 47 to 63 Hz, AC input and up to 165-W DC output from 90 VAC to 265 VAC and 140 W at 85 VAC. The EVM can be used as it is delivered without additional work to evaluate a transition mode boost PFC converter. This user’s guide provides basic evaluation instruction from a viewpoint of system operation of a stand-alone PFC boost power converter.

Features

  • Unified algorithm for working in critical mode (CRM) and discontinuous conduction mode (DCM) with a high power factor across the entire operating range
  • AC input voltage from 85 to 265 VRMS
  • AC line frequency from 47 to 63 Hz
  • Up to 165-W output power
  • High efficiency
  • TM, DCM control gives improved light-load efficiency
  • Burst mode for reduced standby consumption
  • Non-linear gain gives improved transient response
  • User-adjustable valley switching
  • Robust full-featured protection including overtemperature protection, brown-out protection, output overvoltage, cycle-by-cycle overcurrent, and gross overcurrent protections
  • Test points to facilitate device and topology evaluation

Typical applications

  • AC adapter front end
  • Set top box, Gaming, Electronic lamp ballast, Digital TV
  • Desktop computing, Entry-level server and web server
