Prototypes delivered overnight
What if you could come up with the design of the components for your new product one day and have a working prototype the next? Well now you can, for dc-to-dc power supplies, wireless applications, and microcontrollers thanks to the features in National Semiconductor's latest WEBENCH design on-line design tool, version 3.0.
WEBENCH is a free, interactive, on-line workbench that permits engineers to select power supply components (for example), do a virtual physical layout, and simulate the design electrically and thermally. The tool integrates supply chain partners (Pioneer Standard in the case of power supplies) to deliver prototype kits overnight to U.S. addresses, and fully assembled and tested custom prototypes in five days. Engineers analyze a design on WEBENCH until optimal and then order the chips, boards, and software for delivery.
In the past, under deadline pressures, "design engineers usually had to go with what worked, but which may have been suboptimal," says National Semiconductor's Phil Gibson, VP of Web business and sales automation.
In WEBENCH, designs are saved in secure accounts where the engineer can review and re-vise them at any time, along with automatically updated documentation. Engineers can share designs with peers, management, purchasing, and customers for approval and review. True on-line design collaboration is not enabled at this time because it is such a "server-intensive" function. The power supply range currently encompasses designs up to 185W using heat sinks or surface-mount designs with variable copper for thermal management.
In other WEBENCH design environments, Easy PLL (phase-locked loop) for wireless offers simulation and customization of reference designs for the 1.8-GHz GSM and 2.4-GHz ISM standards. The service simulates RF and Aux frequency PLL and loop filter designs. The site can be used for easing selection of flash microcontrollers and visually configuring on-chip peripherals, registers, and interrupts. One feature is the library of pre-configured Embedded Java Beans for each peripheral/controller core combination. It even creates functional code with minimal knowledge of underlying controller complexity.

RF test sockets
These radio frequency (RF) test sockets, complete with spring-loaded lids, are used in RF/microwave, automated handling, and burn-in/life testing applications. The company's Microstrip Contact(TM), used on the sockets, fits pitch devices with up to 208 leads and has a low dielectric strip for lead placement accuracy. Mix-and-match springs from .50 to over 25 lbs. may also be used for the test sockets for precise pressure measurements.

FS, HS, AS, and MX solid-state relays are for industrial use. The FS series is chassis mountable, measuring 0.83 x 1.4 x 0.9 inches, and has an output current rating of 280 V ac. The HS series is designed for mounting on printed circuit boards with a maximum current of 10A. Its thermal efficiency and thyristors are said to handle high inrush currents. AS series relays offer zero cross or random switching for high current overloads. Applications include vending machines, light and lamp control, and fan speed control. The MX series offers an output current rating of 4A to 240V ac for DIN rail mounting. The relays are available in two- or three-pole configurations. Applications include fan speed control, contactor drive, and HVAC.

The Kipster miniature peak pressure indicator is an alternative to electronic instrumentation for fluid and gas systems. The indicator includes a threaded mount body with .25-inch hex drive, an operating pressure range of 2,000 - 8,000 psi, and a pressure-sensitive disk made to deform irreversibly, proportional to pressure. Peak pressure is found by comparing the deformation to a relational graph.
