Overview: In this on line seminar, we
will show you how to design a DC to DC power supply using the award winning
WEBENCH on line design environment. WEBENCH can be used to create a power
supply design in a few minutes using components which are calculated based
on your needs. In addition, if you have specific optimization requirements,
you can use WEBENCH to tune your design. This optimization process involves
tradeoffs of different parameters such as loop stability, output voltage
ripple, maximum current and transient overshoot/response. We will show you
how to quickly explore these tradeoffs to create a design which is optimized
for your needs using the WEBENCH Electrical Simulator. We will also discuss
tradeoffs which can be investigated using the WebTHERM thermal simulator,
such as using a heat sink, PC board copper or a fan to dissipate heat and
get the temperature within spec. Lastly, we will show you how to rapidly
construct a physical prototype of your design using a custom kit which can
be received overnight.

Topics covered in this online seminar include:
- How to choose the best regulator for your specifications
- How to use on line SPICE electrical simulation to optimize your design
- Improve the feedback loop stability using the Bode Plot
- Reduce the output voltage ripple
- Reduce overshoot during load transients
- How to use on line thermal simulation to solve temperature issues
- Is a heat sink necessary, and if so, what type is best. How much
will this cost and how big is it?
- Can PC board copper be used to lower the temperature?
- Is a fan required?
- Use of WEBENCH to get a custom prototype kit overnight
Presenter: Jeff Perry is the
manager of the WEBENCH software development team. He has been involved with
WEBENCH since its inception. Prior to that he worked in wafer fabrication
process engineering. He graduated from UCLA with a physics degree and has
an MBA from San Jose State. |
