Rugged, High-Integration, High-Reliability TFT-LCD Power Supplies Lower Costs in Powering Automotive Displays

ISL78020, ISL78022 Automotive Grade TFT-LCD DC/DC Power Supplies With Integrated Amplifiers Are AEC-Q100-Rated, TS16949-Compliant and Feature Multiple Functions to Save Board Space

MILPITAS, CA--(Marketwire - March 5, 2008) - Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced the release of the ISL78020 and ISL78022, two new Automotive Grade TFT-LCD DC/DC regulators with Integrated Amplifiers that incorporate multiple IC functions into a single, rugged solution.

The devices are AEC-Q100-rated, fully ISO/TS 16949:2002-compliant and operate over the automotive temperature range (-40 degrees C to +105 degrees C) with high integration to improve performance and reduce costs associated with powering 7-to-15 inch displays.

With higher voltage capability ( > 20V) than competitive automotive TFT-LCD power supplies, the ISL78020 and ISL78022 are protected against voltage spikes generated by stray capacitance, as well as against parasitic inductances that occur during the switching operation. This higher voltage capability eliminates a common reliability issue found in other existing solutions.

These new power supplies also feature integrated sequencing, regulated charge pumps, an 18V/3A integrated boost FET, VCOM amplifiers and fault protection features to save board space and BOM costs of additional discrete solutions.

The ISL72022 also integrates five gamma amplifiers.

The ISL78020 and ISL78022 come in thin 7mm x 7mm TQFP packages that withstand greater levels of vibration compared to other package designs. This package also allows automotive electronics designers the ability to actually inspect the pins during PCB assembly, further assuring reliability.

Pricing and Availability

The ISL78020 is available now in a 32-lead, 7mm x 7mm TQFP package and is priced at $2.71 per unit in 1,000-unit quantities and $2.73 per unit in tape-and-reel configuration. More information on the ISL78020 is available at:,1477,ISL78020,0.html

The ISL78022 is available now in a 32-lead, 7mm x 7mm TQFP package and is priced at $4.07 per unit in 1,000-unit quantities and $4.10 per unit in tape-and-reel configuration. More information on the ISL78022 is available at:,1477,ISL78022,0.html
