Abstract:
A power supply control circuit for use in a power supply is disclosed. An example power supply control circuit includes a power switch coupled between first and second terminals. The first terminal is to be coupled to a positive input supply rail of the power supply. The second terminal is to be coupled to an energy transfer element input of the power supply. A sampling circuit is coupled to a third terminal. The sampling circuit coupled to sample a signal across the energy transfer element input of the power supply during an off time of the power switch to provide a sampled output of the power supply. The sampled output of the power supply is disabled from being be resampled by the sampling circuit during an on time of the power switch. A control circuit coupled to the sampling circuit and the power switch, the control circuit coupled to switch the power switch in response to the sampled output of the power supply.
