Abstract :
The operation and performance of a four-switch buck-or-boost converter are presented with peak efficiencies greater than 90% under various loads. The converter is demonstrated in a module format where the single inductor is embedded within the laminated module substrate. Nominal inductance is 2 μH and dc resistance is 120 mΩ. The converter provides a fast-acting current limit function when the sensed inductor current exceeds about 1 A.
