Abstract:
The present embodiments relate generally to power controllers, and more particularly to synthetic current hysteretic control of a buck-boost DC-DC controller. In one or more embodiments, an asynchronous controller of a buck-boost converter implements a state diagram for controlling PFM-PWM and Buck-Boost transitions with minimal circuitry and power consumption.

Claim (Index 1):
A buck-boost controller, comprising:\n a state machine that implements a state diagram for controlling transitions between a buck mode and a boost mode of operation of the buck-boost controller based on window crossing signals from a window comparator; and a multiplexer for selectively sending control signals to switching transistors of the buck-boost controller based on an output of the state machine.
