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
3
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
