Overview

UCD3138 Hard Switched Full Bridge (HSFB) topology firmware gets a designer through evaluation to production in power supply designs based on high power Hard Switched Full Bridge topology by providing all-inclusive firmware with input voltage feed forward, copper trace current sensing, on the fly dead time and switching frequency adjustment and startup into pre-bias.

Features

This firmware comes with native support for following features:

  • Excellent voltage regulation and line regulation
  • Input voltage feedforward
  • Output voltage soft start with pre-bias
  • Load current sharing
  • Copper trace current sensing with temperature compensation
  • Oversampling Function for Enhanced Transient response
  • Fully programmable dead-time for efficiency optimization
  • Constant power/constant current overload protection
  • Cycle-by-cycle current limiting
  • Short-circuit protection with automatic re-start
  • PMBus1.2 (400 KHz) for telemetry

 What’s Included:

  • Application demo code
  • EVM and firmware documentation
