Synchronous Inverse SEPIC Topology Provides High Efficiency Buck/Boost Voltage Converters

Demand is increasing for efficient noninverting dc-to-dc converters that can operate in either buck or boost mode—with minimal cost and component count. The inverse SEPIC (single-ended primary inductor converter) is ideal for this function. An analysis of its operation and implementation with the ADP1877 dual-channel synchronous switching controller will reveal its many useful properties.
