I'm using
MAX756 as a DC-DC boost converter to provide 3.3V from of a single 1.5 AA battery. I've implemented the circuit on page 1 of datasheet with 1N5819 instead of 1N5817 and 144uF caps between Vin and Gnd instead of 150uF. Also Vin comes from bench power supply.
I've tested three 22uH inductors with different current capabilities (all above the required 1.2A due to datasheet (page 6).
~SHDN and
3/~5 is connected to
out.
LBO is left open.
The problem is the Vout is 3.3V in no-load. But as soon as I insert the n * 220 Ohm resistors in parallel, Vout drops and in Iout = 60mA, the Vout drops below 2V.
Here is the picture of the setup: lower rail in Vin and upper rail is Vout

I've shown the other two inductors that I tested.
Anyone knows where the problem might be?
Thanks in advance.
P.S. I've also posted this question
