Rad-hard hybrid point-of-load switching regulators for satellite applications introduced by Modular Devices

SHIRLEY, N.Y., 24 Nov. 2010. Modular Devices Inc. in Shirley, N.Y., is introducing the compact 5080 Proton rad-hard 100K+ high-efficiency synchronous buck regulator that delivers on-board, low-voltage DC power to critical loads precisely where needed. The device develops as much as 10 Watts in a range of low-voltage outputs from an intermediate 12-volt DC input, and achieves operating efficiencies more than 90 percent.

SHIRLEY, N.Y., 24 Nov. 2010. Modular Devices Inc. in Shirley, N.Y., is introducing the compact 5080 Proton rad-hard 100K+ high-efficiency synchronous buck regulator that delivers on-board, low-voltage DC power to critical loads precisely where needed. The device develops as much as 10 Watts in a range of low-voltage outputs from an intermediate 12-volt DC input, and achieves operating efficiencies more than 90 percent.

The hybrid point-of-load switching regulator is radiation hardened, and resists the effects of single-event upset (SEU). The MDI 100K+ Proton rad-hard converters eliminate the use of optocouplers to make the most of proton resistance. Through-hole circuit board and chassis-mount packages are available.

The device has a small conduction-cooled hermetic package, and is designed to power field-programmable gate arrays (FPGAs) at the system specific location in satellite and space electronics. 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.

5080s are available in a range of grades starting with the engineering units for laboratory development use. Space flight parts, which are environmentally screened and qualification tested, operate in temperatures as hot as 125 degrees Celsius.
