Broadband TelCom Power,
Inc.
Redefining “Current” Limits In Power Conversion
48Vin ±12Vout ±0.625A
Description
The S15 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, 5, 12 or 15 Volts. All models feature an input filter,
input
undervoltage
lockout,
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.
