constant current 1.5a

Hi all,
I need a constant current 1.5A for battery charging using a MC34063A IC and an external power transistor that may be MJE3055 or N-MOS.

Regards,

Fernando
 

the best possible way to incorporate the mc34063 is using FETs

why not look for the article of SILICONCHIP magazine issue with DC-to DC converter in it

it can charge lead acid battery at a constant rate.

just my opinion
 

leinahtan,

Very thank you for tip. I'll try to get a copy of this article.

Regards,

Fernando
