The new OM955XSPP series of open-frame, single-output, switching
regulator modules each deliver up to 3A of output current from a 5V
supply. Available output voltages are 3.3V, 2.5V, 1.8V and 1.5V. These
low-cost, high-efficiency DC-DC converters provide point-of-use power
to ASIC, DSP, PLD, PGA and CPU chips in systems utilizing distributed
power architectures. The versatile OM955XSPP’s are easy to use
devices, in a SIP configuration, that require no external filtering (input
and output capacitors are on board). They provide the user with a
"complete" solution for point-of-load regulation power conversion
applications.
These DC-DC converters utilize chip-on-board technology thereby
allowing them to be the smallest (highest power density) 10W,
non-isolated devices available in the market today. These switching
regulators can be used in a wide range of military, industrial and
commercial applications including telecommunications, datacom, radar,
control systems, aircraft display panels, high-density data storage and
test equipment. These devices overall cost effectiveness, performance,
long-term reliability and small size are attributes that collectively could
prove to be beneficial in your next power system design. Evaluate a
sample today … and see for yourself.
