Release Information

Welcome to the LM25190/LM5190 synchronous buck controller with CCCV regulation design tool. This stand-alone tool facilitates and assists the power supply engineer with design of a DC/DC buck regulator based on the LM25190/LM5190 synchronous buck DC/DC controller. As such, the user can expeditiously arrive at an optimized design to meet the application requirements.
