Constant current 1.5A for battery charging with MC34063A

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
