The WEBENCH® Optimizer Dial enables engineers to "dial-in" their preference for footprint, system BOM cost and power efficiency.
The first solutions presented by the WEBENCH Optimizer Dial are set by default at level 3 for a balanced design solution with a focus on ease of design, and a balance between small footprint and high efficiency. For each subsequent click on the Dial settings you can continue to compare additional circuits or architectures for each dial setting. The performance of each of these solutions will be presented to you visually in graphs or tables highlighting Footprint, Efficiency, and total component BOM cost at the 1K budgetary level for complete solutions that meet your desired circuit performance.
The Optimizer Dial adjusts the selection of every component in every circuit solution to meet your desired system performance. The system values of the best design that meets your requirements is shown in the boxes just beneath the Optimizer Dial. For expert optimized circuits in minutes, start your WEBENCH design today!
Philosophy of the WEBENCH Optimizer Dial
1 - Highest Frequency, Smallest Possible Footprint
With switching frequencies at their highest levels, the smallest possible components are selected.
2 - Higher Frequency, Smaller Designs, with a Strong Focus on Low Cost
The switching frequency is pushed higher to reduce the size of components and the highest weighting is given to low cost BOM selections. This is typically the lowest cost design in a small footprint.
3 - Default Setting
The focus here is on a low risk balanced design where Efficiency, Footprint, and BOM Cost have equal weight in the selection of the regulator and supporting components. For the devices with adjustable frequencies, the center frequency is selected.
4 - Lower Frequency, Larger Designs, with a Strong Focus on Low Cost
The switching frequency is pushed lower to minimize switching losses. The result is that peak efficiencies are increased, but larger components are required. This level typically provides the Lowest Cost BOM for a High Efficiency design.
5 - Lowest Frequency, Highest Possible Efficiency Design
With switching frequencies at their lowest levels, components are selected for the highest possible design efficiency.
