Overview

Welcome to the LM25183 and LM25184 quickstart design tool. This standalone tool facilitates and assists the power-supply engineer with the design of a DC/DC flyback regulator based on the LM25183 and LM25184 PSR flyback converter. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.
Features
  • Select transformer parameters including turns ratio and mag inductance
  • Determine input and output capacitances for specified ripple requirements (1% VOUT and 5% VIN)
  • Select components for feedback, soft-start, input UVLO and temperature compensation
  • Advise components (usually optional) for primary winding voltage clamp and flyback diode snubber
  • Optimize the design using efficiency and solution size as key performance metrics
  • Inspect converter efficiency and switching frequency over load and line
  • Analyze efficiency based on selected component parameters
  • Review auto-generated schematic and BOM list
