Abstract
A power management unit comprises a controller, an oscillator circuit, and a monitoring circuit. The controller is configured to control operation of a power converter circuit in a low power mode and an active mode. The oscillator circuit is configured to generate clock signals in the low power mode to control the operation of the power converter circuit. The monitoring is circuit configured when in the low power mode to receive a regulated output voltage from the power converter circuit, compare the regulated output voltage to a specified voltage threshold, and turn off the oscillator circuit when the regulated output voltage is greater than the specified threshold voltage and turn on the oscillator circuit when the regulated output voltage is less than the specified threshold voltage.
