Layout Recommendation for inverting DC-DC Converter MC34063

I am using the MC34063ECD-TR to take 5V and make -12V. I'm using the schematic as recommended in the datasheet for this application (with the exception of using a 100uH inductor instead of a 90uH inductor). It is working nicely electrically - I get...

Can STEVAL_POE002V1 work as 24V source?

I bought the STEVAL_POE002v1. It works fine at 5 V. Now I want to setup a POE with 24V. Can I achieve this with that STEVAL? I would think to change the transformer and to adjust the Feedback-path and perhaps the Fsw. Can you help me with a calculati...

STM6600 VCCLO

The description of the VCCLO pin says it goes low when Vcc is below Vth+.However, the timing diagrams 20 and 21 show VCCLO going low tdebounce after VCC drops below Vth-.Which is correct?

Acoustic Noise L6599

I absolutely do not understand under what conditions and for what reason sometimes during operation of the LLC converter, the power transformer emits audible high-frequency acoustic noise. Some instances work fine, but some make a good audible noise....
