DESCRIPTION
The PTEA series of power modules are single-output
isolated DC/DC converters, housed in an industry
standard 1/8^thbrick package. These modules are
rated up to 66 W with a maximum load current of
20 A.
The PTEA series operates from a standard 48-V
telecom central office (CO) supply and occupies only
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
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.
