Converter and Method

摘要

In accordance with an embodiment, a DC-DC converter is provided comprising a single regulation loop that drives a control circuit, wherein the control circuit selects between operation in a pulse width modulation operating mode and a pulse frequency modulation operating mode, the single regulation loop including a compensation loop, and wherein biasing of the compensation loop is maintained in response to selecting between the pulse width modulation and the pulse frequency modulation operating modes.
