iWatt, Inc., a provider of digital power IC systems products and technology, today announced the release of the iW3620 Digital Controller for LED lighting applications. It is the industry’s first LED driver IC for 5-40W luminaires with primary side regulation that eliminates the need for an opto-coupler and related components thereby reducing bill-of-material cost and improving reliability.

The iW3620 is designed for both the residential and commercial lighting markets for retrofit incandescent and halogen lamp replacement with solid-state lighting. The device’s high frequency operation enables the LED driver module to fit directly inside space-constrained T5, T8, T10 or T12-size fluorescent tubes or MR16 and PAR30 retro-fit incandescent and halogen lamp replacement housing.

The high performance iW3620 Digital Constant Current Controller is based on iWatt’s patented digital control technology which features up to 40W of power management for high efficiency, low EMI, and a simplified design to reduce component count that minimizes manufacturing costs.

iWatt also announced that Civilight, a leader in LED lighting products in China, has chosen the iW3620 for their products’ lighting applications. "We have evaluated and selected the iWatt iW3620 because it delivers a lower price and higher performance," said Mr. Zou De Zhi, Research and Development Manager for Civilight, "iWatt`s IC expertise made them the clear choice."
