I want to start new thread about related question.
The customer already collected dozen of chips which has the following symptoms:
- Different switching frequency.
- 50/50 startup
- Doesn't star at all
Could you please check attached spreadsheet with different tabs from customer.
There are tests of protection diodes inside, scopes and schematics. Please review this.
There are not so much comments, but the customer is ready to have a call to discuss these cases.
Please let me know if you have any concerns or you need more information.
Thank in advance for help.
