The inductor, at 3.3ljH for 5A, is physically at least five times smaller than inductors found in competing solu- tions. All N-channel construction and synchronous rectifi- cation result in reduced cost and highest efficiency. Efficiency exceeds 90% over a wide range of loading, eliminating the need for heatsinking. Output capacitance requirements are low, reducing board space and cost.
