Quick Start Calculator for the LM5140-Q1

LM5140ADESIGN-CALC

Overview

Welcome to the LM5140-1 quickstart design tool. This standalone tool facilitates and assists the power supply engineer with the design of a DC/DC synchronous buck converter based on the LM5140-Q1 current-mode controller. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.

Features
  • Determine filter inductance and input and output filter capacitances
  • Optimize the design using efficiency and solution size as key performance metrics
  • Select components for soft-start, output voltage  and compensation
  • Inspect converter efficiency and component power dissipation
  • Analyze efficiency based on selected component parameters
  • Review auto-generated schematic, BOM, and bode plot
