Overview

Welcome to the LM5175 quick-start design tool. This standalone tool facilitates and assists the power supply engineer with design of a DC/DC buck regulator based on the LM5175 buck-boost PWM 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
Select components for current sensing, soft-start, UVLO, and dither
Optimize compensation values and pole/zero placement in terms of current-mode control loop stability using crossover frequency as a performance metric
Enter relevant parameters for all four power MOSFETs
Inspect regulator efficiency and component power dissipations vs. line and load
Analyze efficiency based on selected power stage components
Review auto-generated schematic and bill-of-materials list
Examine PCB layouts for EVMs and reference designs
