A report describes two radiation-hard application-specific integrated circuits (ASICs) that constitute a mixed-signal chip set that performs all the control functions for a power-converter module (PCM) in a spacecraft power-supply system. One of these ASICs serves mainly as a pulse-width modulation (PWM) controller for the circuitry on the primary side of a transformer in the module; the other ASIC is mainly a synchronous rectifier controller (SRC) for the circuitry on the secondary side of the transformer.

This work was done by Barbara Lam, Clint Kwa, David Zhu, Gene Wester, Gregory Carr, John Bennett, Lauro Franco, David Hogue, Pete Skelly, and Russ Haskell of Caltech for NASA’s Jet Propulsion Laboratory.
