Replacing the Candle in the Candelabra

April 05, 2013 // By Andrew Smith, Power Integrations, Inc.

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.
