Hi
Seeking a very low parts count (< 10 parts), unregulated, isolated, 10W DC/DC converter.
The only purpose of this circuit is to provide isolation, not regulation.
Input: 12V - 24V
Output: approx 4V - 9V, 2A
i'd like to do this with a switched-mode power supply, to minimize heat and size.
My reasons to reduce parts count are:
It happens that a divide-by-3 circuit would keep my output in desired range.
12V/3=4V
24V/3=8V.
The concern then is whether temperature or load could cause deviation outside my desired output-range.
Hoping for a short-height of all parts (especially inductor): < 5 mm. i can be more flexible on inductor footprint (length, width). So, a MHz clock rate would be preferred.
As always, cost is a consideration. Hoping to achieve this for about $5 total.
Any suggestions?
thx

My reasons to reduce parts count are:
- to reduce overall PCB footprint
- simpler for the designer to build it
