what is smps based charger
i used that...i could find nothing...apart from on some app notes on texas site.....its a great chip but poorly served on info...........
But i ask you , does the 3906 power up first (it should) before the batt voltage is connected up?
remember........also how does it work if battery of the wrong voltage is connected the wrong way round, when its initially completely discharged?
and what about a ruined battery......one thats sulphated to hell and back...what if i connect that to your charger?
and what about feedback compensation.......3906 has compensatory R and C....how are yuo going to set these?.
and what happens when i buy your charger, and i leave a fully charged battery connected up and then switch off all the power to the factory cuzz im going home ....does your batt slowly discharge through the feedback divider?
