The RG28B power converter converts a 28 VDC input to a regulated 19 VDC output voltage. This converter is capable of delivering 280 continuous watts at 14 VDC (20A output). The 14 VDC output is buck converted from the input voltage; and therefore, the output voltage is not isolated from the input. A state of art ""synchronous current mode switching"" topology with surface mount technology facilitates the power conversion process. Control circuit with a synchronous PWM controller provides for voltage regulation and current limit. Circuit protection includes an output short circuit current limit and shuts down when the voltage feedback loop is opened.
