Abstract
Systems and methods for improving efficiency in a power management circuit are disclosed. In one aspect, a ping-pong sample and hold circuit smooth transitions from buck to boost (and vice versa) modes of operation for a direct current-to-direct current (DC-DC) converter in the power management circuit. The ping-pong sample and hold circuit provide a ramp compensation for each clock cycle, where transitions are smoothed by holding the last value used from the previous mode of operation. In a second aspect, a current sensor is used that integrates a current value to provide a base feedback loop for the DC-DC converter and may use various compensation factors to provide a proper ramp signal for the DC-DC converter.
