Power Integrations Introduces 75 W Single-Stage Driver for LED Lighting - Raises Street Lamp Drivers Efficiency to over 92%

Power Integrations, maker of the world's most efficient, longest-lasting off-line LED driver ICs, today announced two new additions to its LinkSwitch™-PH IC family. The new devices allow commercial lighting applications up to 75 W to benefit from single-stage design, dramatically reducing BOM cost and enabling a smaller driver with very high efficiency.

LNK410EG (dimming) and LNK420EG (non-dimming) provide a constant-current output with a PF- corrected and low THD input. The capabilities of the new devices are showcased in RDR-290, a reference design describing a single-output driver for high-bay lighting.

RDR-290 is 92.2% efficient at 230 VAC for a 75 W output design while easily meeting EN61000-3-2 class C limits. Power factor is above 0.95. No primary high-voltage electrolytic bulk capacitor is required, making lifetimes of 50,000 hours practical, even in challenging outdoor environments and at high ambient temperatures.

Comments Andrew Smith, product marketing manager at Power Integrations: "By greatly increasing the power capability of single-stage conversion, the efficiency and longevity benefits of the single-stage approach can now be applied to industrial and commercial LED lighting - the market that most needs those characteristics."
