Claim 12:
13. The method of claim 8, further comprising transitioning from the bypass mode to one of the discharge-buck mode and the charge-boost mode by:
starting in an initial state with the first power switch, the second power switch, the third power switch, and the fourth power switch off based on first, second, third, and fourth pulse width modulated signals and the first and second bypass switches on; and
sequentially transitioning the third power switch on, the second bypass switch off, the first power switch switching on and off at a duty cycle greater than zero and less than one based on the first pulse-width modulated signal, the first bypass switch off, and the second power switch switching on and off at a duty cycle greater than zero and less than one based on the second pulse-width modulated signal.
