Description
The PT4660 Excalibur鈩?Series
is a 30-A rated, dual-output isolated
DC/DC converter that combines
state-of-the-art power conversion
technology with unparalleled flex-
ibility. These modules operate from
a standard telecom (鈥?8 V) central
office (CO) supply to produce two
independantly regulated outputs.
The PT4660 series is characterized
with high efficiencies and ultra-fast
transient response, and incorporates
many features to facilitate system
integration. These include a flexible
鈥淥n/Off鈥?enable control, output
current limit, over-temperature
protection, and an input under-voltage
lockout (UVLO). In addition, both
output voltages are designed to meet
the power-up/power-down sequenc-
ing requirements of popular DSPs.
The PT4660 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
鈥楴鈥?configuration occupies less than 2
in虜 of PCB area.
