New Dual 100V Linear Regulator Saves Board Space and Cost for Telecom Applications

MILPITAS, Calif.--Intersil Corporation (now Renesas Electronics), a designer and manufacturer of high-performance analog semiconductors, recently announced what is reported to be the industry's first dual 100V linear regulator, the ISL6719. According to the company, the new regulator provides steady, accurate voltage for a wide variety of applications, such as telecommunications and networking systems. Its highly integrated architecture enables the IC to handle the functions of up to 15 discrete components. But because of its small 3mm x 3mm, high thermal-performance DFN package, it requires less than half the board space of a comparable solution based on discrete chips, the company says.

The company expects that the ISL6719's high level of integration and carefully selected features will allow system designers to simplify their design process, improve overall system reliability and efficiency, and reduce cost. It is said to be the only dual 100V (input) product currently on the market.

The ISL6719 is suited for use as a single start-up linear regulator in isolated power designs, or as a dual-output bias supply for point-of-load regulators in telecom and datacom applications. The control circuitry used in telecom and 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.
