초록
A buck-boost converter using a delta-sigma modulator (DSM) includes a buck-boost mode driving circuit configured to receive an input voltage and output an output voltage according to an operation mode, a mode controller configured to sense an output of the buck-boost mode driving circuit and determine the operation mode, and a gate driver configured to receive a mode determination signal for determining the operation mode from the mode controller and control switches included in the buck-boost mode driving circuit. Accordingly, output ripple characteristics thereof can be improved.
