TI LM5145EVM-HD-20A

DC/DC, Step Down5V24 В ~ 72 В

Overview

The LM514575-V synchronous buckcontroller is designed to regulate from a high input voltage source or from an input rail subjectto high voltage transients, minimizing the need for external surge suppression components. Ahigh-side switch minimum on-time of 40 ns facilitates large step-down ratios, enabling the directstep-down conversion from a 48 V nominal input to low-voltage rails for reduced system complexity and solution cost. TheLM5145EVM-HD-20A continues tooperate during input voltage dips as low as 6 V, at nearly 100% duty cycle if needed, making itwell suited for high-performance industrial control, robotic, datacom, and RF power amplifierapplications.

The LM5145controller is offered in a 3.5-mm × 4.5-mm thermally-enhanced, 20-pin VQFN package with additionalspacing for high-voltage pins and wettable flanks for optical inspection of solder jointfillets.
