Redefining “Current” Limits In Power Conversion
BTCPower
SQO/SQ Series
Description
25A High Efficiency Quarter Bricks
The SQO/SQ series of high power density, high efficiency
DC/DC converters deliver up to 25A in an industry standard
quarter-bricks footprint. With a wide input voltage range of
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, output overvoltage and
overtemperature protection, output current limiting and short
circuit protection. These converters are available either in a
package that is open-frame / enclosure construction. The
aluminum heat spreader design achieves very efficient heat
transfer with no hot spots. The use of highly derated power
devices help to achieve high reliability, high performance
and offer a low cost solution to systems designers that are
challenged to maximize power and minimize board space.
