DESCRIPTION
The PTQA4300xx series of power modules are
single-output isolated DC/DC converters, housed in
an industry standard quarter-brick package. These
modules are rated up to 100W with a maximum load
current of 30 amps.
The PTQA4300xx series operates from a standard
48-V telecom central office (CO) supply and
occupies only 3.3 in2 of PCB area. The modules offer
OEMs a compact and flexible high-output power
source in an industry standard footprint. They are
suitable for distributed power applications in both
telecom and computing environments, and may be
used for powering high-end microprocessors, DSPs,
general purpose logic and analog.
Features include a remote On/Off control with
optional logic polarity, an undervoltage lockout
(UVLO), a differential remote sense, and an industry
standard output voltage adjustment using an external
resistor. Protection features include output
overcurrent protection (OCP), overvoltage protection
(OVP), and thermal shutdown (OTP).
The modules are fully integrated for stand-alone
operation, and require no additional components.
