Power Integrations recently develops a new LinkSwitch™-PH LED Driver IC, DER-278.

Power Integrations’ efficient, accurate, single-stage, primary-side-control technology, featured in LinkSwitch products, eliminates both the electrolytic capacitor and the also-unreliable optocoupler used in traditional isolated flyback designs. Designers using LinkSwitch-PH ICs for SSL products can expect the operational life of the driver to exceed the 35,000 hours required by the ENERGY STAR SLL (V1.1) specification.
 
Suitable for designs from 5 W to 55 W, SSL driver ballasts based on LinkSwitch-PH ICs achieve greater than 90% energy efficiency and satisfy the ENERGY STAR® requirement of >0.9 power factor.
 
It is available in high-reliability industrial, commercial, and exterior solid-state lighting applications.
