PTEA420033 20-A, 48-V Input, Isolated, 1/8th Brick DC/DC Converter |

PTEA420033 (NRND) 20-A, 48-V Input, Isolated, 1/8th Brick DC/DC Converter



The PTEA series of power modules are single-output isolated DC/DC converters, housed in an industry standard 1/8thbrick 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.
