NATIONAL Semiconductor, represented by Arrow Electronics , has launched two new switching regulators tailored for high-voltage power supply designs for communications, industrial and automotive applications.

By combining advanced high-voltage processes, chip-scale packaging and proprietary circuitry, National Semiconductor offers the industry's first fully integrated switching regulator ICs that operate from 10 volts to more than 100 volts.

"National's new high-voltage power products address the evolving and demanding power conversion requirements of next-generation systems for our major customers," said Paul Greenland, marketing director for National Semiconductor's Power Management Group.

"The LM5000 family provides engineers with all-in-one solutions for reliable, high performance and cost-effective power system design. In light of the positive feedback we've already received from customers, we are confident the LM5000 family will become a preferred power solution for high-voltage systems."

According to the Darnell Group, a leading power management market research firm, the global communications power market is expected to grow from $US4.4 billion in 2003 to $US5.8 billion in 2008, a compound annual growth rate (CAGR) of 5.5 percent.

In units, the market is expected to experience a CAGR of 11.2 percent during the same period.

Currently, communications application-specific integrated circuits (ASICs) deploy deep sub-micron technologies that require a sub 2V power source at high current.

At the same time, power demand is increasing along with the number of the ports per board and speed of communication.

National's LM5000 is a fully integrated, current-mode, pulse-width modulation (PWM) dc-dc regulator that operates with a wide range of input voltage between 3.1V and 40V.

A built-in 80 V power DMOS transistor is rated up to 2 A peak with a channel resistance of 200mW. The versatile LM5000 operates at user-selectable frequencies up to 1.25MHz.

The LM5000 offers high-density, high-efficiency power conversion solutions in telecommunications, automotive, networking, industrial, and battery-powered applications.

The world's first 100V, high-frequency current-mode dc-dc controller, the LM5030 is a PWM controller with all the features to implement state-of-the-art Push-Pull and Bridge topologies.
