Dear All,
I have designed a boost regulator(DC to DC converter) for my laptop using LM3478. My source is a 12volt/30ah Lead acid battery.
With no load the circuit is working perfect. However when the circuit is loaded(when connected to the laptop) its not delivering enough current. I tried connecting with both acer and thoshiba latop. Both cases its not delivering more than 500mA and its not charging the battery at all.
I have used National Work bench onlline design software for design assistance and followed the same circuit based on that. Also gone thorugh the datasheet of LM3478 and couldnt make out where the problem is.
If you have encountered the same issue, Please suggest me the options to tackle this issue.
Thanks to all for your assistance in advance,
Regards,
Kuttan
