100-W 20-A Programmable Isolated DC/DC ConverterThe PT4484 Excalibur DC/DC
converter module combines state-of-the-
art power conversion technology with
un-paralleled flexibility. Incorporating
high efficiency and ultra-fast transient
response, these modules provide up to
20A of output current over the program-
mable voltage range of 4.6V to 5.7V.
The modules include a number of
inbuilt features to facilitate system
integration. These include a foldback
output current limit, over-temperature
protection, and an inhibit on/off control.
A differential remote sense is also provided
to compensate for voltage drop between
the converter and load.
For additional output current, one
PT4484 may be operated with up to two
PT4498 compatible booster modules.
Each PT4498 adds an additional 20A of
output current capability. By Texas Instruments
