PT4100—48V

SLTS021A

(Revised 1/16/2001)

15 Watt Isolated DC-DC Converter

• 15W Output Power ⁽¹⁾

• Input Voltage Range:

36V to 75V

• 1500 VDC Isolation

• Low-Profile

The PT4100—48V series of dc/dc

converters provide up 18 Watts/in of

isolated power in a single low-profile

module. Designed to operate from a

standard 48V telecom bus, these modules

employ switching frequencies of up to

850kHz, planar magnetics, and surface-

mount construction. They are designed

for Telecom, Industrial, Computer, Medical,

and other distributed power applications

that require input-to-output isolation.

• Current Limit

• Short-Circuit Protection

• Over-Temperature Shutdown

• UL1950 recognized

• CSA 22.2 950 certified

• Meets EN60950
