Description
The PT4410 series of power modules are single-
output isolated DC/DC converters, housed in a
compact 21-pin low-profile (12 mm) package.
These modules are rated up to 100W with load
currents as high as 30 A. The output voltage is set
within a pre-defined range via a 5-bit input code.
The PT4410 series operates from a standard
48-V telecom CO supply and occupies only 3.9 in2
of PCB area. These modules offer OEMs a compact
and flexible high-output power source for use with
high-end microprocessors, DSPs, general purpose
logic and analog. They are suitable for distributed
power applications in both telecom and computing
environments.
Features include output over-current protection,
on/off control, output over-voltage protection
(OVP), over-temperature shutdown, under-volt-
age lockout (UVLO), and an output differential
remote sense. The modules are fully integrated
for stand-alone operation, and require no additional
components. The horizontal package outline is also
comparable to industry standard -bricks, allowing
for a dual PWB layout.
