Description

Ordering Information

current limit, over-temperature pro-

tection, and an input under-voltage

lock-out. In addition, both 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

in² of PCB area.

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
