Power Integrations Introduces 75W Single Stage Driver for LED Lighting

Power Integrations, the world's most efficient and longest-lived manufacturer of off-line LED driver ICs, announced on August 28 that it has added new devices to its LinkSwitchTM-PH IC product line. The new device benefits commercial lighting applications up to 75 W from a single-stage design, dramatically reducing BOM cost and enabling very compact smaller drives.

LNK410EG (dimming) and LNK420EG (non-dimming) provide input with constant current output with PF and THD correction. The specific features of the new device are described in the RDR-290. This reference design describes a single output driver for high bay lights.

The RDR-290 is designed for a 75 W output with an efficiency of 92.2% at 230 VAC and easily meets EN61000-3-2 Class C limits. The power factor is greater than 0.95. The design eliminates the need for primary side high voltage bulk electrolytic capacitors, making it possible to achieve a 50,000 hour service life, even in challenging outdoor environments and high ambient temperatures.


Andrew Smith, Product Marketing Manager, Power Integrations, said: "By dramatically increasing the power capability of single-stage conversion, the high efficiency and long life of the single-stage design approach can now be applied to industrial and commercial LED lighting – and this is the most needed The market for this feature."

Win 3 Cap Lamps are produced under IECEX quality control. The lamps are applied with IECEX explosive-proof certificates, build with brilliant electronic design and superior  impact resistant, explosion-proof housing material, It is completely static proof and fire resistan.


The high quality LED has a lifespan of more than 30,000 hours and the phosphate technology battery up to 1000 cycles.

Small size and light weight, easy to carry
The highest ingress protection IP 68
Various application: coal miners, tunnel projects, oil fielda , camping, hiking, night fishing, night flying, sailing, etc.
