As you can see, the VCC pins of the two GaNs both come from the VDD in the upper left corner, but they have different reference GND, so how are the two GaNs powered?
Part Number: TIDA-01623 Hi, Good day. Our customer is looking at the TIDA-01623 and they have noticed a problem on the PCB layout. They said that the silk screen is on the pad as shown below. We would appreciate if you could confirm if this is observation…
Part Number: TIDA-01623 Other Parts Discussed in Thread: UCC28070 Hi, sir, could you tell me the PCB layout principle? How do you do the PCB layout? What factor we should consider?
Part Number: TIDA-01623 Hi team,
I got a question from customer.
This picture clearly shows the difference of waveforms between ACF and QRF. Why has the spike on VSW disappeared? and why can the ACF achieve full ZVS but QRF not?
Thank you very much for…

Part Number: TIDA-01623 Hello,
We are looking for a concept for the d esign of a PS used for a display supply, 5V, 16A, 80W with the following voltage range input: nominal input 110V DC +-30% = 77-143VDC. Ambient temperature is up to 80°C.
The concept…
Hello Harish,
Thank you for the comprehensive response. I really appreciate it.
It appears that I do not need High voltage start circuitry start up or IC for the configuration example that you mentioned. The other reference design - TIDA-01623 ( www.ti…
