LM25145 Datasheet (Texas Instruments) - 6-V to 42-V Synchronous Buck DC-DC Controller

LM25145, 6-V to 42-V Synchronous Buck DC-DC Controller

The LM25145 42-V synchronous buck controller is designed to regulate from a high input voltage source or from an input rail subject to high voltage transients, minimizing the need for external surge suppression components.

A high-side switch minimum on-time of 40 ns facilitates large step-down ratio
