Description

The PT4220 power modules are a

series of DC/DC converters housed in

an ultra-low profile (8mm) solderable

copper case. The series includes a num-

ber of preset output voltages ranging

for Telecom use. T hey may also be used

in many other applications that require

input-output isolation over an extended

temperature range. The modules are an

ideal choice for low-power digital and

analog circuits, including DSPs and

microcontrollers. The flexibility of

input-output isolation also allows the

output to be configured for negative

voltage operation.

The PT4220 series is made available

in both horizontal and vertical pin con-

figurations, including surface mount.
