Welcome to the quickstart design tool for the LM5149, LM5149-Q1 and LM25149, LM25149-Q1. This standalone tool facilitates and assists the power supply engineer with the design of a DC/DC buck regulator based on the above controller family. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.
- Determine output filter inductance and input and output capacitances
- Select components for input UVLO, OCP, output voltage setpoint and AEF
- Optimize compensation values and pole/zero placement in terms of control loop stability using crossover frequency as a performance metric
- Inspect regulator efficiency and component power dissipations
- Analyze efficiency based on selected power MOSFET parameters
- Review auto-generated schematic, BOM list and solution size estimate
