how can we design power supply using MC34063 for boosting 6V to 12V and provides 12V@1A.

How can you make anything without looking at the datasheet???nikhil arora said:how can we design power supply using MC34063 for boosting 6V to 12V and provides 12V@1A.
try a bigger inductor, and make sure it's a power inductor, and not an RF choke
the only 'critical' parts I've run into on these things, is (A) the switch itself and (B) the output capacitor ... you're probably right about the ESR of your 2200uF cap being too high
its Rsc resistor for current limmiting lesser it is more current u can draw before ic shutdowns it self.also, it could be your piece of wire for the osc resistor has the clock running too fast, and the switch and/or diode can't handle it?
the input is from battery 6V,4.2Ah and i have connected 1000uF at input.also, where is the 6v coming from ... do you have sufficient input capacitance?

I donot know whether it is Rf choke but it is like a 1/2W resistor with color band markings.
I donot know it power handling capacity.

i am using IRF540 and a 2200uF electrolytic capcitor.
the input is from battery 6V,4.2Ah and i have connected 1000uF at input.

I have few more inductors

so which type of inductor should I use
