Hi,
I understand that OP1 is your output device.
If you are going to operate OP1 as a linear device, rather than a PWM switching device, can you give me some ball park figures.
Around OP1.
What will Vcc, its supply voltage be?
What will be a typical output voltage of OP1 for say a 12V lead acid battery, that is being charged at 10A?
