PT4100—24V

SLTS020A

(Revised 1/15/2001)

15 Watt Isolated DC-DC Converter

• Input Voltage Range:

18V to 40V

• 1500 VDC Isolation

• Low Profile

• Current Limit

• Short-Circuit Protection

• Over-Temperature Shutdown

• UL1950 recognized

• CSA 22.2 950 certified

• Meets EN60950

The PT4100—24V series of dc/dc

converters provide 18 Watts/in³of isolated

power in a single low-profile module. De-

signed to operate from a standard 24V

telecom bus, these modules employ

switching frequencies of up to 850kHz,

planar magnetics, and surface-mount con-

struction. They are designed for Telecom,

Industrial, Computer, Medical, and other

distributed power applications that require

input-to-output isolation.
