+30V DC-DC converter

I introduce the compact DC-DC converter in this page. I found this converter at the junk shop. I attempted to examine the characteristic of this converter.
The input voltage is +5 V, the output voltage is +30 V and can get the about 20-mA output current.
The IC(CD-1846P) to be using with this converter becomes the manufacturing stop already. However, TDK said that it was the discontinuation part and I could not acquire the data.
Because it may become the reference when you use the similar circuit, I introduce in the contents of the converter.
