Overview

UCD3138 non isolated bi-directional switching converter quickly gets a designer through evaluation to production in power supply designs based on a Wide Vin non isolated bi-directional topology by providing all-inclusive firmware with ZVS Transition mode support.

Features

This firmware comes with native support for following features:

  • Transition mode supported as wells as Hard-switching.
  • ZVS Control at Low Line for light load efficiency
  • Phase sync and DPWM engine enables hardware based control.
  • Interleaved up to 4 phases in single chip
  • Phase shedding and adding for light load as well as adaptive dead time optimization for efficiency improvement
  • PMBus 1.2 with 400 KHz for telemetry operations.

  • Application examples
  • EVM and firmware collateral
