LED driver IC manufacturer PI launches 75W single-stage driver
July 01, 2023
San Jose, California, USA – Power Integrations, Inc., the world’s most efficient and long-life manufacturer of off-line LED driver ICs, is today announced as its LinkSwitch? - PH IC product line adds new devices. The new device will enable commercial lighting applications up to 75W to benefit from a single-stage design, resulting in a significant reduction in BOM costs and smaller drives that achieve extremely high efficiency.
LNK410EG (dimming) and LNK420EG (non-dimming) provide constant current output with PF and THD correction. The specific features of the new device are described in RDR-290. This reference design describes a single output driver for high bay light.
With a 75 W output design, the RDR-290 has an efficiency of 92.2% at 230 VAC, while easily meeting EN61000-3-2 Class C limits. The power factor is greater than 0.95. The design does not require the use of a primary-side, high-voltage, high-capacity electrolytic capacitor, which makes it possible to achieve a power supply life of 50,000 hours, even in challenging outdoor environments and high ambient temperatures.
Andrew Smith, product marketing manager for Power Integrations, said: "By boosting the power capability of single-stage conversions, the high efficiency and long-life benefits of single-stage design methods can now be applied to industrial and commercial LED lighting. The market for this feature."
