Power Integrations Launched 75 W Single-Stage LED Lighting Driver

Power Integrations has added two new devices to its LinkSwitch™-PH IC family for LED Lighting.

The new devices allow commercial lighting applications up to 75 W to benefit from single-stage design, reducing BOM cost and enabling a smaller driver with 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.
