TPS544B25 Datasheet Synchronous Buck Converters

Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & munity Reference Design TPS544C25, TPS544B25 SLUSC81 – MAY 2015 TPS544x25 4.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS544x25 devices are PMBus 1.2 pliant, non-isolated DC-DC converters with integrated FETs, capable of high-frequency operation and 20-A or 30-A current output from a 5 mm × 7 mm package.

Highfrequency, low-loss switching, provided by an integrated NexFET™ power stage and optimized drivers, allows for very high-density power solutions.

The PMBus interface enables the AVS through VOUT_MAND, flexible converter configuration, as well as key parameters monitoring including output
