Power Integrations has developed two new circuits that are ideal for worldwide LED industrial and commercial lighting applications requiring best possible performance.
Two compact, efficient bulb-replacement design ideas. By moving to a buck boost topology, PI is able to achieve a combination of performance that has not been possible up to now. Previously if a design was required to deliver very high efficiency, a high output voltage was required. However, this concession to efficiency resulted in unacceptably low power factor and total harmonic distortion that made such solutions unusable for worldwide lighting applications.
