LM5166 DC/DC Converter Design Tool

LM5166DESIGN-CALC

Overview

Welcome to the LM5166 Quick-Start Design Tool. This standalone tool facilitates and assists the power supply engineer with design of a DC/DC buck converter based on the LM5166 low IQ synchronous buck DC/DC regulator. 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 for a given operating mode (PFM or COT)
  • Optimize the design using efficiency and solution size as key performance metrics
  • Select components for soft-start, input UVLO, output voltage setpoint, current limit and switching frequency
  • Inspect converter efficiency, solution size, component power dissipation, switching frequency, and output voltage ripple
  • Analyze efficiency based on selected component parameters
  • Review auto-generated schematic and BOM list
  • Determine EMI filter components
