Intersil Adds New 100V Linear Regulator For Telecom Applications

January 03, 2008 by Jeff Shepard

Intersil Corp. announced the ISL6719, a 100V linear regulator that complements Intersil’s recently released 100V triple output linear regulator, the ISL6720A. The new regulator is said to provide steady, accurate voltage for a wide variety of applications such as telecommunications and networking systems. With its highly integrated architecture, the new IC handles the functions of up to 15 discrete components, but its small 3 x 3 millimeter high thermal performance DFN package means it requires, according to the company, less than half the board space of a comparable solution based on discrete chips.

The company claims that the ISL6719 will allow system designers to simplify their design process, improve overall system reliability and efficiency, and reduce cost. ISL6720A and ISL6719 are described as the industry’s first 100V linear regulators that offer a total biasing solution in such a small package for isolated power telecom/datacom applications.

The ISL6719 is suitable for use as a single start up linear regulator in isolated power designs, or as an output bias supply for point-of-load regulators in telecom/datacom applications. The company claims that the control circuitry used in telecom/datacom applications typically requires an operating bias voltage significantly lower than the source voltage available to the converter, and thus many applications require a discrete linear regulator. When implemented discretely, this circuitry occupies significant space, a considerable problem in today’s high-density converters. The ISL6719 linear regulator simplifies the start-up and operating bias circuitry needed in telecom and datacom dc-dc converters by integrating these functions and many other features into an extremely small IC.

The ISL6719 is available in a 9 Ld 3 x 3mm DFN package in quantities of 100-999 for $1.25, or in a 9 Ld 3 x 3 DFN T+R package for $1.27.
