ABSTRACT |
Tests were performed on space-qualified, point-of-load (POL) regulators to evaluate potential performance and reliability issues in their space use. For fiscal year (FY) 2010, two models of POL regulators were tested - a radiation-hard, low-drop-out linear regulator used in multiple flight applications, and a radiation-hardened, variable-output, synchronous buck regulator, which is intended for future flight applications. Some tests were performed at the thermal military extremes and below. Measurements performed include efficiency, regulation, load transient response, synchronization, and turn-on tests. |
