Description

Ordering Information

protection, and an input under-

voltage lockout. In addition, both

output voltages are designed to meet

the power-up/power-down sequenc-

ing requirements of popular DSP

ICs.

The PT3660 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

in² of PCB area.

The PT3660 Excalibur™ 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 (–48V) central

office (CO) supply to produce two

independantly regulated outputs.

The PT3660 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

current limit, over-temperature
