Onsemi NCP1623 | Demoboard NCP1623PFC150WGEVB

Enhanced, High-Efficiency Power Factor Controller

Overview

TopologyPower Factor Correction
Input voltage90-264 V

Description

This design provides high power density 150W CrM Boost PFC. The controller NCP1623 enables to drive without aux. winding ZCD sensing by Novel Drain sensing tech. Two level follower boost feature help to improve low line input efficiency. And Disable function in 8SOIC option helps to improve standby power. With those features this EVB provides USB PD optimal design.

Features

  • Valley Synchronized Frequency Fold−back (VSFF):
  • CrM at Heavy Load
  • DCM at Light Load by Dead Time Control
  • Valley Switching in Both CrM and DCM
  • On−time Modulation for High PFC in Both CrM and DCM
  • Follower Boost Capability (NCP1623A Only)
  • Lowered Output Voltage Regulation at Low Line
  • High−Efficient Boost Stage and Downsized Inductor Design
  • Skip Mode for Light Load Regulation
  • Sleep Mode with Low Current Consumption (SOIC8 Only)
  • Fast Line / Load Transient Control
  • Dynamic Response Enhancer at Output Undershoot
  • Soft OVP and Fast OVP at Output Overshoot
  • Excessive Current Protection
  • Over Current Protection (OCP)
  • Over Stress Protection (OVS)
  • Brown Out Protection
  • Second Over Voltage Protection (OVP2)
  • These are Pb−Free Devices

Typical applications

  • Flat TV
  • Industrial Power Supplies
  • USB−PD
