Part Number: TIDM-02008
Other Parts Discussed in Thread: TIDA-01606,
This is the 8th time we pose the same question with no decent answer. We get answers for a spectrum of issues apart from our issue.
The question is;
In regard to the programmability of the DC out of this reference design what is the topology limit.
We know that;
- One limit/constraint on the regulated output DC voltage is the rating of the power switches
- a 2nd limit on the regulated DC output is the losses (which increase as increase the rating of the power switches)
- a 3rd limit on that output is the rating of the capacitors.
We certainly know that we have to ensure that the ratings these components (and all other components) have to be considered, and we will do that. We certainly know also that you only documented what you already tested and we appreciate that. Further, we also know that if we change the DC output of that design we might have to re-design resistors, capacitors or inductors.
The question remains;
Does the topology (or the design concept) itself places a limit on the variation range of the DC side?
For example if the input AC voltage is 220 VAC can we get a regulated DC output voltage= 1000VDC (assuming we rate all the components properly and assuming we will re-design the inductors and every every other component we need to be re-designed)? If not, what is the constraint?
We are seeking topology limit. We are not seeking components limits NOR we are asking for any test results apart from the ones documented.
