PTEA404120

SLTS274A – DECEMBER 2006 – REVISED JANUARY 2007

50-W, 48-V INPUT, 12-V OUTPUT, ISOLATED DC/DC CONVERTER

• 50-W Output

The PTEA404120 power module is a single-output

isolated DC/DC converter, housed in an industry

• Input Voltage Range: 36 V to 75 V

standard one-eighth brick package. This module is

• 91% Efficiency

rated up to 50 W with a maximum load current of

• 2000 V

4.2 A.

• On/Off Control

The PTEA404120 operates from a standard 48-V

• Overcurrent Protection

telecom central office (CO) supply and occupies less

• Differential Remote Sense

compact and flexible high-output power source in an

industry standard footprint. They are suitable for

• Output Overvoltage Protection

distributed power applications in both telecom and

• Over-Temperature Shutdown

computing environments, and may be used for

intermediate bus converter architectures.

• Undervoltage Lockout

Features include a remote On/Off control with

• Standard 1/8-Brick Footprint

optional logic polarity, an

undervoltage

lockout

• UL Safety Agency Approval

(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.
