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.
