LM5180 PSR flyback converter design tool
LM5180DESIGN-CALC
Overview
Welcome to the LM5180 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 LM5180 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 SW 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
