BTCPower
S25 Series
25W High Efficiency Low Power Bricks
Description
The S25 series of high efficiency, low power DC/DC
converters offer power levels that exceed other bricks with
similar footprint. With a wide input voltage range of 18-36 or
36-75V they are available with an output voltage of either
1.5, 1.8, 2.5, 3.3, or 5 Volts. All models feature an input filter,
input undervoltage lockout, overtemperature protection,
output current limiting and short circuit protection. The fully
enclosed, encapsulated construction 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 that are challenged to maximize power and
minimize board space.
