Emerson Adds Astec 75 Watt Model to Popular Surface-Mount Point-of-Load (POL) DC/DC Converter Family

Non-Isolated SMT Converter Features Flexibility with Programmable Wide Input Range, Compact Footprint and Up to 92 Percent Efficiency

CARLSBAD, Calif. - September 9, 2004 - Emerson Network Power, a business of Emerson (NYSE:EMR) has added a new 75 Watt model to its popular Astec ( ), APC surface-mount product line of point-of-load (POL) DC/DC converters. With an input voltage range of 10VDC to 14VDC, the new APC18 models provide up to 18 Amps (A) of regulated power with efficiency as high as 92 percent. Using the same compact open-frame package as the 25 Watt and 40 Watt APC Series models, the devices feature an industry-standard, surface-mount (SMT) footprint only 1.3 inches long (33.02mm) by 0.53 inches wide (13.46mm). Only 0.35 inches high, the devices are ideal for use in environments with the most restrictive space requirements and can often serve as drop-in replacements for existing APC Series applications that have increased power requirements. Competitive pricing and compact size allow the new APC18 models to replace discrete designs using less board space and minimizing the time-to-market for DSP and ASIC applications.

The flexible single-output APC18 devices simplify purchasing decisions with adjustable external resistor programming that enables a single part number to provide a selected output voltage from 0.75VDC to 5.5VDC with regulation to within 3 percent. With the wide input voltage ranges, these devices are well-suited for a variety of POL applications. For added flexibility, each unit has its own enable pin to allow for sequential activation. Additionally, every unit has built-in overcurrent and overtemperature protection, with auto-recovery from any protective shutdown once a fault is removed.

The wide operating temperature range of -40 to +85 degrees Celsius makes the APC series suitable for use in extreme environments as well as for applications such as data and telecommunications. The devices are also well suited for instrumentation, internetworking devices such as hubs and routers, test equipment and any applications where that rapid time-to-market is a priority.

Priced from $11.50 in OEM quantities, samples are available now. For more information, contact an Astec Power representative in your area. To locate a representative, go to the Astec Power Web site at, and click on the SALES OFFICES button on the home page.
