Buck PFC Pre-Regulator in Power Factor Correction Applications

Overview

TopologyPower Factor Correction
Input voltage90-264 V
Output 184 V / 1.2 A
IC revisionA

Description

The UCC29910AEVM-730 is a fully assembled and tested circuit for evaluating the UCC29910A buck power factor correction (PFC) controller. Using buck PFC topology, the UCC29910AEVM-730 converts a 90VAC to 264VAC input, with 47Hz to 63Hz frequency, to an 84VDC output with a maximum output power of 100W.

Features

  • Buck Power Factor Correction for High Efficiency Across Line
  • Low Off-Line Startup Current, with SmartStart Algorithm for Fast Startup With Soft-Start
  • Compatible With Resistive or Pass Transistor Fed Startup from the AC Line
  • Low Power SmartBurst Mode for Standby and Light-Load Conditions
  • Current Sense Inputs for PFC control and Overload Protection
  • Line Sense UVLO
  • Sense and Drive Control for External Startup Depletion Mode FET
  • Latching Fault Input Pin

Typical applications

  • High Efficiency AC-DC Adapters
  • Low Profile and High Density Adapters
