SLUSC81 – MAY 2015 TPS544x25 4.5-V to 18-V, 20-A and 30-A SWIFT™
Synchronous Buck Converters with PMBusв„ў and Frequency Synchronization
1 Features 3 Description The TPS544x25 devices are PMBus 1.2 Compliant,
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 Г— 7 mm package. Highfrequency, low-loss switching, provided by an
integrated NexFETв„ў power stage and optimized
drivers, allows for very high-density power solutions.
The PMBus interface enables the AVS through
VOUT_COMMAND, flexible converter configuration,
as well as key parameters monitoring including output
voltage, current and an optional external temperature.
Response to fault conditions can be set to either
restart, latch-off or ignore depending on system
requirements. PMBus 1.2 Compliant Converters: 20 A and 30 A
Input Voltage Range: 4.5 V to 18 V …
