Abstract
A switched mode power supply having a regulated reflected voltage. In one circuit, a power switch is coupled between first and second electrical terminals. An energy transfer element is coupled to the first electrical terminal of the power switch. A power supply rail is coupled to the second electrical terminal. A control circuit is coupled to the energy transfer element and to the power switch. The control circuit is to switch the power switch in response to a signal derived from a voltage at the energy transfer element to regulate an output of the circuit.
