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
