Hi-Rel DC-DC POL Buck Regulators
Peregrine’s PE9915x devices are radiation-hardened point-of-load (POL) buck regulators with integrated switches suited for DC-DC converter applications. These devices offer radiation hardness up to 100 KRad (total dose tolerance) and Single Event Effects (SEE) immunity to a Linear Energy Transfer (LET) greater than 90 MeV•cm²/mg. This monolithic technology replaces multi-chip modules by offering superior performance, smaller size and reduced weight in sensitive space applications.
These integrated buck regulators contain synchronous switches capable of delivering up to 2A, 6A or 10A of continuous current. The PE9915x are designed to operate from a wide 5V bus and provide 1.0V to 3.6V supply rails for analog, digital and RF payloads.
