LM5145 Datasheet (Texas Instruments) - Synchronous Buck DC-DC Controller

LM5145, Synchronous Buck DC-DC Controller

The LM5145 75-V synchronous buck controller regulates 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 gives large step-down ratios, enabling the dire
