摘要：
Traditionally, buck-boost switching regulators with bridge topologies have been avoided due to their inability to seamlessly transition between buck mode and boost mode. Here, however, a buck-boost switching regulator with a bridge topology has been provided, which has an improved controller. Namely, a processor (such as a digital signals processor or DSP) provides digital control for the bridge that reduces ripple current or variations in the inductor current by adjusting phase relationships between corresponding buck and boost switches in a bridge or buck-boost mode.
