REDUCING OUTPUT VOLTAGE RIPPLE OF POWER SUPPLIES

摘要

Reducing output voltage ripple of power supplies. In some embodiments, an electronic circuit may include a first node configured to receive an input signal proportional to an output voltage produced by a power supply, a second node configured to receive a reference voltage configured to alternate between two voltage values during operation of the power supply, and a third node configured to output an enabling signal configured to control the operation of the power supply in response to a comparison between the input signal and the reference voltage. In other embodiments, a method may include turning on a power supply in response to a falling ripple being smaller than a first reference voltage value, and turning off the power supply in response to a rising ripple being greater than a second reference voltage value, where the second reference voltage value is smaller than the first reference voltage value.
