Broadband TelCom Power,
Inc.
Redefining “Current” Limits In Power Conversion
Technical Specification
48Vin 2.5Vout 7.0A
Description
The S25 family of high efficiency, low power DC/DC
converters offer power levels that exceed other bricks
with similar footprints. They are targeted specifically at
the telecommunication, industrial electronics, mobile
telecommunication and distributed power markets.
With a wide input voltage range of 36-75V they are
available with output voltages of either 1.5, 1.8, 2.5,
3.3 or 5 Volts. All models feature an input filter, input
undervoltage lockout, output overvoltage and
overtemperature protection, output current limiting and
short circuit protection. The fully enclosed,
encapsulated construction with aluminum heat
spreader design achieves very efficient heat transfer
with no hot spots. The use of patented design
concepts facilitate maximum power delivered with the
highest efficiency up to 90%. The converters combine
creative design concepts with highly derated power
devices to achieve very high reliability, high
performance and low cost solution to systems
designers requiring maximum power in small
footprints.
