hai i am using mc34063 in my project as stepup dc-dc converter.
input range is 3.5 to 4.5dc. out put is 24v, 80mA.
as per datasheet, its input voltage recommended is 3v to 40v dc.
I calculating all values, input peak current not exceed 1.5AMP.
i am mentioning calculated values:
Rsc=0.22ohms
Rc=180ohms
inductor=47uH,200ma
timing capacitor=330pF
output capacitor=220uF
R1=1.1k
R2=20k
please validate this circuit.
one more thing, i am using this 24v,80mA for constant current source 30ma and to activate the three 24vdc relays.
