Estimating the term…
A method may include, when in a low-power mode of a power converter, monitoring an output voltage of the power converter; comparing, with a single comparator, the output voltage to a first threshold voltage and cause the power converter to enter a magnetization phase of the low-power mode responsive to the output voltage falling below the first threshold voltage; and during the magnetization phase and a demagnetization phase of the low-power mode, comparing, with the single comparator, the output voltage to a second threshold voltage lower than the first threshold voltage and cause the power converter to enter the high-power mode responsive to the output voltage falling below the second threshold voltage.
A system comprising:
A method, in a system having a power converter for regulating an output voltage at an output of the power converter and power management circuitry configured to enable operation of the power converter, including one or more first components critical to operation of the power converter in a high-power mode and one or more second components critical to operation of the power converter in both the high-power mode and a low-power mode in which the system consumes significantly less power than that of the high-power mode, the method comprising, when in the low-power mode:
