Hybrid Point-of-Load switching regulators are Rad-Hard space savers for satellite applications

Shirley, NY November 23, 2010 -- Modular Devices, Inc., the leader in hybrid power conversion for space and aerospace electronics announces availability of compact Proton Rad Hard 100K+™ high efficiency synchronous buck regulators.

The Model 5080 delivers reliable on-board low voltage DC power to critical loads precisely where needed. Developing up to ten watts in a range of low voltage outputs from an intermediate 12 Vdc input, the 5080 POLs achieve operating efficiencies of over 90 percent. Their small low profile, conduction-cooled hermetic package make system design and integration simple. Powering FPGAs at the system specific location, the 5080s offer satellite and space electronics system designers new options for volume and weight savings. "Model 5080 fills the need for efficiently providing a low voltage, high current source to power radiation hardened applications," said President, Steven Summer.

Standard features include inhibit for logic level on-off control, frequency synchronization, built in test, current telemetry and interconnects for easy, reliable paralleling for higher current output and N+1 redundancy.
The flight heritage design is SEU resistant (LET>82MeV*cm²/mg) and radiation hard (TID>100kRadSi). The MDI 100K+™ Proton Rad Hard converters eliminate the use of optocouplers to maximize proton resistance. Both through-hole PCB and chassis mount packages are available.

5080s are available in a range of grades starting with the engineering units for laboratory development use. Space flight parts, which are fully environmentally screened and qualification tested, are the optimum choice for 125°C continuous duty high reliability space applications. The factory offers complete applications assistance and supports comprehensive data sheets and application notes for reference. "The Model 5080 introduces the MDI POL series to support critical applications which demand increased high performance and efficiencies from your power source" Summer states.

Since 1973, Modular Devices, Inc. has specialized in providing space electronics systems designers, integrators and specifying engineers a wide variety in custom, semi-custom and off-the-shelf hybrid dc-dc power conversion products and power systems.
