Description

General part information

PTQA420050 Series

The PTQA 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 up to 30 A.

The PTQA series operates from a standard 48-V telecom central office (CO) supply and occupies only 3.3 in2of 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).
