I have 12V 7.2 AH Sealed lead acid battery and want to make a charging circuit from a transformer. please suggest me a simple and best circuit which will give right charging current and voltage. No PWM...
hi i want to design an boost conveter in range 4.3v to 7.1 volts .. ouput 15v at current of 750mA .. plz suggest me any circuit..
and i have to drive all circuitary on input supply only.. i.e.4.3v to 7.1 volts only no bias supply ..
thanx a lot for that. i will try and reply here . but as how much minimum possible voltage across the 3055 as suppose my battery voltage is 4.2volt then i think its not possible to have 0.2 voly across transister
thats what i need.

as i need consatnt 4 volt from 6 volt so most preferred ck is of converter using inductor but i don't want to use it .. that's why i m asking

i have 6 volt 4.5Ah battery and want to drive 30 White LED 5mm each LED @ 40mA current with constant current .
but my problem is that i have not to use any inductor in the circuit. plz suggest me any circuit.
see image i have to give regulated 4 volt to this array from 6 volt battery
i have made this project Heart rate measurement from fingertip :Embedded Lab now i want to show same result on pc also and want to save it for different persons .. can it be possible? if yes plz help me..
