A boost converter approach to lighting applications allows the creation of the smallest volume converter possible and enables high efficiencies beyond 90%. The device incorporates a current sense comparator with a fixed offset enabling a simple hysteretic control scheme free of the loop compensation issues typically associated with a boost converter. The integrated OVP and VCC regulator further simplify the design procedure and reduce external component count. 1 • • • • • Simple Hysteretic Control Compact Solution and Simple Bill Of Materials Naturally Dimmable TRIAC and Reverse Phase Dimmers Implements LED Drive Circuits Capable of High >90% Efficiency, >0.9 Power Factor, and
