DESCRIPTION
The PTEA415050 power module is a 5-V,
single-output, isolated DC/DC converter, housed in
an industry standard one-eighth brick package. This
module is rated up to 75 W with a maximum load
current of 15 A.
The PTEA415050 operates from a standard 48-V
telecom central office (CO) supply and occupies less
than 2.0 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
intermediate bus converter architectures.
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 module is fully integrated for stand-alone
operation, and requires no additional components.
