Overview

Welcome to the LM5116, LM5116WG and LM25116 Quickstart Design Tool. This standalone tool assists the power supply engineer with the design of a DC/DC buck regulator based on a synchronous buck controller from this product family. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.

Features
  • Determine values for the power stage components, including buck inductance and input and output capacitances
  • Select the ramp capacitor value for peak emulated current-mode control
  • Review components for soft-start, input voltage UVLO, current sensing and output voltage setpoint
  • Optimize compensation values and pole/zero placement in terms of control loop stability
