TI is committed to continually improving the online design experience. As a part of that commitment, we are excited to invite early adopters and engineers around the world to try out our first of a suite of future HTML5 applications—the new WEBENCH® Power Designer (Beta). In this post, I will walk you through the new enhancements, designed to help you make power design decisions faster and easier.
The input form
The first thing you’ll notice is our new re-designed input form displayed in Figure 1 below. You can use this form to quickly look up a TI device that you may have in mind or start your search using basic inputs. The advanced settings are now organized to guide you toward designs meeting any criteria, and the optimization knob is now a Design Consideration toggle

Select a design screen
The first step in the power design process is to select your design. WEBENCH Power Designer previously calculated operating values and generated a thumbnail of what the schematic may look like. New optimized algorithms now enable you to generate full power designs. Our large selection of filters lets you narrow down which design would best fit your needs. For users who are used to the original flash version, there’s still a table view option. However, a new card view, pictured below in Figure 2, is the default view in the selection step.
This card view has additional features that enable you to:

The compare designs feature
Figure 2 above shows the new selection screen with check boxes on each design to compare designs. This new feature generates a table, displayed in Figure 3, with additional information such as integrated circuit (IC) parameters and IC features which enables a side-by-side comparison of multiple designs.

The customize, simulate and export design steps from our former version of WEBENCH Power Designer have been split from a single screen into three new screens, with logical steps to guide you through the power design flow.
Figure 4 below is a screen shot of the new Customize screen. You will notice that you can view your design upfront, customize parameters to the left, and see the effects of your customizations in operating and performance below. You will also see in Figure 5 that we have removed the optimization knob. The removal of the optimization knob simplifies the process by calculating the design values upfront for comparison purposes so that you can make the best decision to meet your optimization needs.

Once you are done customizing, you can verify your design by running an electrical simulation in the next screen. Finally, you can move on to the export screen which displays an overview of your final design with clear buttons to prompt you to export to your most used CAD tools, print a design PDF report, or circle back to TI.com for more information such as downloading a datasheet, going to the TI Store, or exploring the product folder.

It's so exciting!
Do you have any document of new WEBENCH that is "How to use"?
Not right now as we wanted the tool to be as intuitive as possible. There are videos and updated how-to content planned coming soon!
Hi, I like new design!!!
By the way, I couldn't find the Re-Comp function. Do you have a plan to add the Re-Comp function?
You can expect to see Re-Comp by the end of the year. We will have a solid date for which release it will go out in in the next month.
this was a real improvement, especially for the Simulation tab! I like the labeling of the currents and voltages which is far better than in previous versions.
Is it possible to separate the simulation waveforms?
how about clock, filter, amplifier, and other ASC tools? will it change to HTML5?
I found it's hard to find this ASC webench tool, but my customer and I used a lot! any plan?
Is thermal simulation planned in new Webbench?
I need dual output design. How t customize in tool. Pls suggest
Hi Suresh Babu, To answer your question on dual output designs. We currently do not support multi-output designs in the new WEBENCH power designer.
Hi Kristaps Ragausis, To answer your question on if thermal simulation is planned in the new WEBENCH power designer, the answer is we have a thermal alerts capability which will alert if your IC's junction temperature or critical power component temperatures exceed. We are not planning a full thermal simulation feature in the new WEBENCH power designer.
Hi Bonnie Chen, to answer your questions on signal chain tools, we will be having the right signal chain tools depending on the product type. As an example, for amplifiers, if you visit the opamps page on ti.com at www.ti.com/.../products.html you will find quick searches and search by circuit functions to help you with selecting the right amplifier. For current sense amplifier as an example, if you visit the product folder, you will find calculator tools to help you with the product. www.ti.com/.../ina190
Hi Hans, to answer your question on separating the simulation waveforms - the answer is we currently do not have the feature to separate the waveforms in separate viewing panels.
