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
from 1.3V up to 12V, all fully approved
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.
