Dallas, Tex. – The race to bring new products to market faster just got a little easier for power supply designers, particularly for time-constrained engineers who often have to work under tight deadlines and are faced with complex design requirements. Texas Instruments (TI) has released three new advanced tools in its online WEBENCH Power Designer that provides experienced engineers with extensive design control, analysis and trouble-shooting capabilities for power-supply designs.
However, the free WEBENCH tools are still aimed at helping newly minted or experienced engineers to quickly create, optimize and simulate a design. Offering a range of tools from control-loop compensation to simulation export, WEBENCH Power Designer helps design engineers create power supplies for industrial, automotive, and communications equipment.
The new advanced WEBENCH tools offer experienced power-supply design engineers extensive control over complex designs, along with easier exporting of simulations to computer-aided design (CAD) platforms from Altium and Cadence Design Systems Inc., said TI.
The new advanced options (watch the video) in WEBENCH Visualizer include a set of controls to help power-supply designers specify complex design requirements, such as manufacturability, component constraints and design control. This helps them find solutions to accurately match their advanced design requirements, said TI.
Addressing unstable control loop, cited as one of the pitfalls of power supply design, the new WEBENCH Compensation Designer tool predicts and automatically corrects errors in the control loop resulting in a stable power-supply design. This quick "fix-it-for-me" feature is a valuable tool for both novice and experienced engineers, dealing with time constraints. “It also offers advanced power experts a manual mode to tune the control loop for more bandwidth and stability in their designs,” said TI.
The new WEBENCH Simulation Export tool moves the power-supply schematic into the user's preferred simulation environment with a few clicks and no intermediary software, according to the company. The tool exports the complete design to the TINA-TI™ simulator or Altium Designer and Cadence OrCAD and PSpice tools. This new tool is in addition to TI's WEBENCH Schematic Export and PCB Export tools, which enable engineers to create their power-supply designs and download the layout directly to five popular CAD tools, said TI.
"With the addition of simulation export capability to WEBENCH Power Designer, engineers no longer need to manually recreate the schematic in OrCAD Capture and gather and enter the SPICE models into the PSpice solution, or worry about errors that plagued the manual process," said Josh Moore, product marketing director for the OrCAD product line at Cadence, in a statement. "Now, the complete simulation netlist and SPICE models created with WEBENCH Power Designer can be easily and instantly downloaded via WEBENCH Simulation Export to Cadence OrCAD Capture and simulated with the PSpice tool."
