have designed the following step up conveter
the only things which are differing are
1>
For Rsc I have used a short wire
2>
I have used 50uH of inductor even I am not sure of its value.
I have inductors but I cannot read their values.
I got 50 by using parallel combination of 100uH but I am not sure they are 100uH or what.
3>Instead of MBR1645
I am uisng 1N5822
Input voltage is 6.4V from a SLA battery. 4.2AH marking
NOW the problem is
1>
when I am connecting a load which just takes 300mA to 400mA the voltages fall from 12V to 6.8V or so
2>
without ouput capacitor and load the voltage at ouput is constant 12V
but when i connect a 2200uF/35V capacitor the voltage fluctuates a little and voltage drop to 11.6 to 11.7Vs
I think this is what they called they need less ESR of capacitor
