The iW7019, an 8-channel LED backlight driver is designed to deliver better screen performance and lower cost in next-generation 2D and 3D LCD TVs has today been introduced by iWatt. The iW7019 gives designers a rich set of integrated features to improve picture quality and render a more lifelike viewer experience. These include both head and tail-mode pulse width modulation dimming to reduce motion blur, and high-resolution, 12-bit local dimming...

iWatt Inc today launched its latest single-stage, solid state lighting (SSL) LED drivers to address cost, performance and lifetime issues in dimmable bulb applications. Following the introduction of its single-stage LED driver for non-dimmable incandescent bulb replacement applications earlier this year, iWatt is debuting the iW3606 (8W output power) and iW3608 (15W output power), giving LED bulb manufacturers an alternative approach to significa...

iWatt expands its PrimAccurate pulse width modulation controller platform to include two new power adapter chipsets that offer the company’s fastest standby recovery. The iW1766 + iW628 and iW1767 + iW628 chipsets provide ultra-low,

iWatt Inc today announced its latest LED driver for LCD TV backlighting. The new iW7011 is a 6-channel LED driver with a built-in intelligent digital control engine, developed to reduce the bill of materials (BOM) cost and simplify design of edge-lit and direct-lit LCD TVs. The digital core of the iW7011 provides on-chip control of the DC-to-DC boost circuit, along with precise LED dimming control and all the monitoring and feedback for the LED d...

iWatt Inc today debuted an innovative digital AC/DC LED driver platform designed to address cost, performance and operating life in commercial and wireless solid state lighting (SSL) systems. The first device in this new platform, the iW3630 is a two-stage, Flickerless™ LED driver with output power up to 45W and is believed to be the first SSL LED driver with a built-in 0V to 10V dimming interface for commercial lighting ballasts. It also suppo...

iWatt Inc today launched an innovative digital AC/DC solid state lighting (SSL) LED driver platform designed specifically to address the key issues of cost and lifetime in price-sensitive, non-dimmable, residential SSL bulb applications. The first device in this new platform is the iW3626, a single-stage driver with output power up to 10W for 60W-equivalent, non-dimmable LED bulbs. The iW3626 allows SSL designers to reduce their bill of materials...

iWatt has raised the bar for no-load standby power consumption and efficiency in 12W to 24W power adapter and charger applications with the iW1761 and iW1762 digital pulse width modulation controllers. These new devices expand iWatt’s latest PrimAccurate controller platform, lowering power draw in standby mode to just 10mW at up to 12W output power (iW1761) and 20mW at up to 24W output power (iW1762).

iWatt Inc today announced its latest digital AC/DC SSL (solid state lighting) LED driver platform with the iW3616 and iW3617. This new platform expands iWatt’s existing line of Flickerless LED drivers, increasing output power to 25W or higher, lowering the bill of materials (BOM) cost by 10% to 20%, and offering compatibility with an even wider range of installed dimmers, including residential TRIAC dimmers as well as the more sophisticated dig...

iWatt has today introduced its latest AccuSwitch primary-side driver with an internal power switch rated to 800V for universal AC input. The new iW1816 digital pulse width modulation driver is designed to support high capacitance loads (up to 6,000µF) at up to 5W. The device also includes an adaptively controlled soft start, which enables fast start-up for a wide range of output voltages from 5V to 12V and higher, while driving a large capacitiv...

iWatt today unveiled its newest PrimAccurate controller platform. The iW1699 is optimized for applications up to 12W with ultra-low standby power of less than 30mW to address the needs of smart phone and media tablet applications. The iW1760 is designed for applications requiring higher power, up to 40W, with less than 50mW standby power, including set top boxes, home networking devices, and a wide range of household appliances.
