Three years ago I designed and build a few tens of intelligent car battery chargers (controlled by microcontrollers) for a company that sells car batteries. The design was using a TOP249 and a 140W flyback transformer (in fact by reading the datasheet of that transformer I found about your company :) ). I wasn't very experienced and that's why the design has a pretty low safety margin but even so, most of those chargers still work until today.
Now I want to improve the original design and produce is a greater number and for a longer time period. Since I have first-hand proof that your SMPS drivers are really good and help in getting a robust and cost-effective product I want to include them in this future design.
Before restarting my research and design I want to ask your opinion on which SMPS topology and Power Integration drivers it would be wise to go on considering these target requirements:
- variable output voltage between 5V to 16V (I want to be able to charge 6V and 12V batteries);
- maximal continuous output current: 10A;
- AC input voltage: 195-265;
- I plan to include a temperature triggered fan to avoid overheating of the transformer and of the driver;
- I want a cost-effective design but I also want at least 5% safety margin (so if the required output power in worst case is 16Vx10A=160W, I want the design to be able to deliver at least 160W x 1.05 ~ 170W).
So kindly please advise me which SMPS topology and Power Integration drivers variant you think suits better my requirement.
P.S. I am aware of your PI Expert suite. I used it in the last design. Unfortunately, not all your products are included in that suite so I can't check by myself what is the best topology/driver for my problem.
