DEMO-IDP2303A-100W

Overview

The evaluation board is a 100W digital PFC-LLC Converter with 85V AC~265V AC input and 19V output. It is controlled by Infineon’s 2 nd generation digital PFC-LLC combo controller IDP2303A. The IDP2303A is specially designed for switch mode power supplies used in TV power adapter  and other adapter applications. 

Summary of Features

  • Integrated startup cell for low standby power
  • Support multi-mode PFC operation for optimized efficiency curve
  • Synchronous PFC and LLC burst mode control with soft-start to prevent acoustic noise
  • Comprehensive parameters for configuring PFC and LLC operation
  • Configurable and comprehensive protection features for PFC/LLC/IC temp
  • IEC62368-1 certified active X-cap discharge function
  • Flexible IC parameter setting with digital UART interface

Benefits

  • No auxiliary power supply needed
  • Low BOM count and samll form factor desing due to high integration of digital control and reduction of external components
  • Easy design of system schematic and PCB layout
  • High system reliability
  • Shorter development cycles and higher design and production flexibility

Potential Applications

  • TV adapter
  • Other power adapters
