AC/DC Converters

iWatt's AC/DC converter products offer both stand-alone digital controllers and digital controllers with integrated power devices to provide an AC/DC power supply for a wide variety of applications including wall adapters and chargers and off-line LED driving applications for solid state lighting.  iWatt's AC/DC products incorporate PrimAccurate™ technology which enables accurate control of a secondary-side voltage from the primary side of an isolated power supply without the need of an opto-isolater, improving reliability, reducing size and lowering total BOM cost. 

iWatt's digital control cores further improve performance by enhancing load and line regulation using real-time waveform analysis, offering a superior level of control compared to analog equivalents.

 

LED Drivers - Solid State Lighting

iWatt's award-winning line of solid-state lighting (SSL) LED drivers uses a digital core to provide the control necessary to convert an AC voltage down to a constant current at a voltage adequate for driving LEDs in applications up to 40W.  The SSL product line from iWatt incorporates PrimAccurate™ technology to offer primary-side control of an isolated power supply which is used to drive high brightness LEDs in light bulbs designed to replace incandescent and flourescent lighting.  The SSL products also incorporate iWatt's proprietary Flickerless™ technology, preventing flicker while maintaining compatibility with the widest range of existing dimming technology, making iWatt's SSL technology backwards compatible with the installed base of lighting dimmers.

 

LED Drivers - Display Backlighting

iWatt's DC/DC regulators are targeted for LCD display backlighting in applications such as LCD TVs, Monitors and Notebook computers. Once again, iWatt incorporates proprietary control techniques in the DC/DC converter product line with BroadLED™ technology, which efficiently matches LED current, allowing for the use of low cost LEDs with wider tolerances on their forward voltage. This innovative technology, combined with advanced analog and mixed-signal technology results in power management products that deliver unrivaled power efficiency and exceptional energy savings.
