Intersil ISL8009: World’s Most Power-Efficient Integrated FET Buck Regulator Extends Battery Life and Saves Space

(PresseBox) ( Milpitas, California, USA, )
Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced the ISL8009, a high-efficiency, 1.5A synchronous buck integrated FET regulator ideal for point-of-load regulation for datacom/telecom, battery powered systems, medical instrumentation and several industrial applications.

The ISL8009 is designed to utilize a special multi-operation capability, allowing selection between forced PWM mode and automatic PWM/PFM mode. This ability to switch between modes enables the regulator to maintain up to 95% efficiency in both full load and light load conditions. Additionally, when the device is in PFM mode, the quiescent current drops to 17μA and makes the ISL8009 ideal for battery powered applications.

The ISL8009 includes features like high 1.6 kHz switching frequency, allowing the use of smaller external components. The device also has internal current mode compensation to eliminate the need for external components while contributing to fast transient response in over current conditions.

Other important features of the ISL8009 include Power-On-Reset (POR) and Enable (EN) to provide output voltage monitoring and power sequencing capabilities, further eliminating the need for additional discrete ICs.

With high integration in a small 2x3 8-ld DFN package, the ISL8009 offers customers a high-efficiency solution in a tiny footprint that occupies less than one square centimeter in area.

Pricing and Availability (for Product Press Release)
The ISL8009 is available now in an 8-lead DFN package and is priced at $1.52 in 1,000-unit quantities. More information on the ISL8009 is available at,1477,ISL8009,0.html
