3 Description

The TPS544B20 and TPS544C20 devices are

PMBus compatible, non-isolated DC-DC Integrated

FET converters, capable of high-frequency operation

and delivering 20-A , or 30-A current output from a

5 mm × 7 mm package, enabling high-power density

and fast transient performance with minimal PCB

area. The PMBus interface provides for converter

configuration as well as monitoring of key parameters

including output voltage, current and an optional

external temperature. High-frequency, low-loss

switching, provided by an integrated NexFET power

stage and optimized drivers, allows for very highdensity

power solutions and reduced inductor and

filter capacitor sizes. Response to fault conditions can

be set to either restart or latch off depending on

system requirements.
