Overview

Welcome to the LM27403 Quick-Start Design Tool. This stand-alone tool facilitates and assists the power supply engineer with design of a DC/DC buck regulator based on the LM27403 voltage-mode PWM controller. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.

Features
  • Determine output filter inductance and input and output filter capacitances
  • Select components for soft-start, UVLO, OCP and OTP
  • Optimize compensation values and pole/zero placement in terms of control loop stability using crossover frquency as a performance metric
  • Inspect regulator efficiency and component power dissipation
  • Analyze efficiency based on selected MOSFET parameters
  • Review auto-generated schematic and BOM list
