Description
The PT4452 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
30A of output current over the program-
mable voltage range of 1.3V to 3.5V.
This represents a full 100W output at
3.3V.
The modules include a number of
inbuilt features to facilitate system
integration. These include output over-
current shutdown (with auto reset),
over-temperature protection, and an
inhibit on/off control. A differential
remote sense is also provided to com-
pensate for voltage drop between the
converter and load.
For additional output current, one
PT4452 may be operated with up to two
PT4495 compatible booster modules.
Each PT4495 adds an additional 30A of
output current capability.
