Re: Help to diagnose SMPS issue

Here is Test circuit for this IC
When i wrote to Renesas to give me test circuit - they
answer : we can send to you datasheet....
Datasheet is very bad explained everiting is too
difficult to be done simple tasks as calculating of frequency
NO OTHER IC WITH MORE STUPID DATASHEET
User not worry how IC works...
He wants to use IC with several simple steps
to be explained adjustment of modes and frequency...
In my case SMPS wont to start stable because optocoupler
in F/B is bad....
