I have built this circuit with the following modifications:
1. I have used 200V zeners instead of the 400V(1N5117) zeners.
2. I have used a bead type 100uH inductor.
I am using a 6V 250mA solar panel. The MAX639 IC is a regulator IC. All resistors are 1/4 watt.
Now, how can I test this circuit. Whether it is working or not???
I don't want to connect Ni-Cd cells(infact i haven't bought them yet). I connected my multimeter accross the output terminals but it simply shows 0Volts? Meanwhile solar panel is supplying 6V to the circuit!
Here is the datasheet of MAX639. It too contains the same circuit.
