FLYING CAPACITOR VOLTAGE BALANCING TECHNIQUES FOR A MULTI-LEVEL BUCK CONVERTER

An apparatus including a buck circuitry and logic circuitry. The buck circuitry charges a flying capacitor with a voltage in response to a device state being in a charging state and discharges the voltage from the flying capacitor in response to the device state being in a discharging state. The logic circuitry causes the buck circuitry to transition the device state in response to detecting voltage balance during a reference time period and causes the buck circuitry to repeat the device state occurring at the reference time period in response to detecting voltage imbalance during the reference time period.
