Guys,
I am trying to build a high voltage source using a DCP010515 DC-DC converters. When powered with 5V, these 1W devices should output about 15V at 66 mA of current. Using 3 devices connected in series and powered by 6V battery, I got about 100V which is kind of high (I expected about 45V). When I connected the 10k resistor to the output, the voltage dropped to about 18 mV and the current measured 1.8 mA. Is it normal to observe such a big voltage drop at the specified resistance?
Thanks,
Anton.

 

I finally solved the problem. Maybe it would be useful for somebody... These converters require the 0.47 - 2.2. uF capacitor at input terminals. I used the capacitors and the problem was solved.
