The PTEA404120 power module is a single-output isolated DC/DC converter, housed in an industry standard one-eighth brick package. This module is rated up to 50 W with a maximum load current of 4.2 A.

The PTEA404120 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 modules are fully integrated for stand-alone operation, and require no additional components.
