Synchronous Buck Converters with PMBusв„ў
1 Features 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 Г— 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. 1 PMBus-Enabled Converters: 20 A, 30 A …
