Have you considered using devices from Linear Technology (now Analog Devices) ? You can run extensive simulations with LTSpice, using accurate models for their ICs (I assume they are encrypted spice models).
I dont do bode plots for any of my designs; instead I rely heavily on spice simulations and run a lot of corner cases, varying component values, etc. As your design improves, you will see that overall behavior is not sensitive to component values. For example, I'm working on a DCDC converter and I had horrible ringing; changing a capacitor value 2X had a major impact on the ringing. After some other fiddling, even a 10X change in capacitance no longer increases the ringing appreciably. One thing to really watch-out for is inductor current; make sure you stay well-clear of the saturation current (Isat) spec for the device. If you are using a transformer (coupled inductors) , make sure your circuit works nicely with non-ideal conditions such as finite DC resistance (usually in the datasheet), and non-ideal coupling (K < 1). All kinds of bugs come crawling out of the woods; much easier to deal with them with a simulator than a real circuit on your workbench. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
