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 or 12 Volts. All models feature an input filter,

input

protection, output current limiting and short circuit

protection.

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.
