Abstract:
A low standby power DC-DC converter can be powered down during standby mode. The DC-DC converter can be periodically awakened between sleep cycles to check if the output voltage needs to be recharged (refreshed). The duration of the sleep cycles can be varied to accommodate for changing load conditions that would affect the output voltage.
