IDP2303A

Overview

Digital multi-mode PFC and LLC combo controllers

The XDP™ IDP2303A is a digital combo controller with integrated drivers and 600V depletion cell designed for boost PFC and half-bridge LLC targeting switched-mode power supplies (SMPS) from 75W to 300W.

Summary of Features

  • Integrated start-up cell for low standby power
  • Support multi-mode PFC operation for optimized efficiency curve
  • Synchronous PFC and LLC burst mode control with so -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 digitalUART interface supports PSU platform approach

Benefits

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

Potential Applications

  • LCD TV power supply
  • General SMPS
  • Power adapter
