Hello.
I use TPS63000 and have some questions.
Condition1. Current conspumtion is under 100mA.
Condition2. Input voltage is 5.0v and Output voltage is 3.3V .
Q1. There is high frequency sound, when I touch by hand on operation.
After that, It keeps draw very high current and seems like it's burned out and never recover. Is it normal?
Q2. I don't use R-C filter for 'VINA'. Is it okay? I don't see any information about this on datasheet.
Q3. There is high frequency sound when start-up sometime.
I attach my schematic and gerber.
Thanks.
