LM5137-LM25137-DESIGN-CALC

Welcome to the quickstart design tool for the LM5137, LM5137-Q1, LM25137 and LM25137-Q1 controller family, which is intended for functional safety applications. This standalone tool facilitates and assists the power supply engineer with the design of a DC/DC buck regulator in a single- or dual-output configuration. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.

• Configure the controller for dual-output, two-phase or multi-phase configurations
• Determine buck inductances and input and output capacitances
• Select components for soft start, overcurrent protection, switching frequency and output voltage setpoint(s)
• Optimize compensation component values for loop stability using crossover frequency as a performance metric
• Inspect regulator efficiency, solution size, and component power dissipations with ambient temperature as a parameter
• Review auto-generated schematic and BOM list
