Vishay Intertechnology Launches PowerCAD On-Line Simulation Tool for Point-of-Load DC/DC Circuits

Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the PowerCAD Simulation tool, a free on-line tool that gives engineers a fast and convenient way to test and optimize DC/DC circuits built with Vishay Siliconix regulator ICs.

Using an intuitive interface, the PowerCAD Simulation tool supports both experienced analog and power designers as well as junior or digital designers with less experience in high-power, high-frequency voltage regulator design.

Based on the required operating conditions, the engineer can select the appropriate regulator from the Vishay product offering and generate a full circuit schematic for the application. The schematic can then be edited as required for more advanced users or for performance comparison purposes.

Once the basic circuit is created, the designer can perform DC, transient, and start-up simulations with visibility of all the circuit node waveforms. An efficiency analysis and optimization of the circuit with detailed power loss analysis may also be performed.

Following these steps, the PowerCAD Simulation tool generates a bill of materials (BOM) available for online ordering, allowing a quick validation that dramatically reduces design cycle times. The circuit simulation can also be shared easily with Vishay FAEs for additional technical support or any other related question.

Regulator ICs supported by the PowerCAD Simulation tool include the Vishay Siliconix microBUCK® family of fully protected high-efficiency, high-frequency step-down voltage regulators. Examples of regulator ICs supported by the tool include the SiC401A and SiC401BCD.

Providing high performance in a compact footprint, microBUCK serves as a cost-effective solution for a wide range of point-of-load (POL) applications having input voltages from 2.7 V to 36 V and handling up to 15 A of load current. The PowerCAD Simulation tool provides on-the-fly simulation for all of the following microBUCK devices: SiC413, SiC414, SiC424, SiC401, SiC402, SiC403, and SiP12107.

The Vishay PowerCAD Simulation tool joins the ThermaSim online thermal simulation tool, reference boards, and other online collateral as part of Vishay’s commitment to serving its worldwide customers as a one-stop shop for power management solutions.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
