Power Integrations has developed a new reference design (DER-278) based on its single-stage LinkSwitch-PH LED driver IC family. The new design eliminates the need for unreliable electrolytic capacitors and opto-isolators, making it especially suited for high-reliability industrial, commercial and exterior solid-state lighting (SSL) applications.
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.
LED-based lighting systems have the potential for a much longer operational life than incandescent or fluorescent bulbs. However, the classical two-stage topology (ie, power-factor plus high-voltage DC-DC converter), which is sometimes used by manufacturers targeting consumer-grade bulb replacements, utilises a high-voltage electrolytic bulk capacitor between the stages. The longevity of such systems is limited by the lifetime of the electrolytic capacitor, which tends to dry out and fail, particularly when situated in an enclosed space (eg, a ballast ‘brick’ or bulb base) and exposed to the heat produced by inefficient two-stage power conversion and proximal high-brightness LEDs.
Power Integrations’ single-stage, primary-side control technology, featured in LinkSwitch products, eliminates both the electrolytic capacitor and the 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.
