Description
The PT4680 Excalibur Series
is a dual-output isolated DC/DC
converter that combine state-of-the-
art power conversion technology with
unparalleled flexibility. Operating
from a (–24V) industry standard input
bus, the PT4680 series provides up to
20 ADC of output current from two
independently regulated voltages
(each output 15 ADC max).
The PT4680 series is characterized
with high efficiencies and ultra-fast
transient response, and incorporates
many features to facilitate system
integration. These include a flexible
“On/Off” enable control, output

voltages are designed to meet the
power-up/power -down sequencing
requirements of popular DSP ICs.
The PT4680 series is housed in
space-saving solderable copper case.
The package does not require a
heatsink and is available in both
vertical and horizontal configura-
tions, including surface mount. The
‘N’ configuration occupies less than 2
