DESCRIPTION

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 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.
