Peregrine Semiconductor unveils new power management products

Peregrine Semiconductor has announced its first power management products are available for sampling: the UltraCMOS-based point-of-load (POL) dc/dc buck regulators with integrated switches.

The trio of radiation-hardened devices, PE99151, PE99153 and PE99155 benefit from Peregrine's CMOS-on-sapphire technology. Peregrine claims the PE9915x POL dc/dc synchronous buck regulators are the industry's smallest space-grade monolithic non-isolated distributed power solution. Single event effects immunity to a linear energy transfer greater than 90 MeV•cm2/mg and radiation hardness of greater than 100kRad (total dose tolerance) make the regulators suited for space, defence and various commercial and industrial applications. Dave Shepard, vice president and general manager for Peregrine's high performance solutions business unit, said: "This is a natural evolution for the Peregrine portfolio based on the success of our rad-hard switches, frequency synthesizers and prescalers in the demanding high-reliability market."
