Part Number: UCC21550 Other Parts Discussed in Thread: UCC21520 Hi team,
Could you provide a UCC21520 and UCC21550 detail comparison table?
Does UCC21550 can replace UCC21520 directly?
or any other solution can replace UCC21520? thanks
Part Number: UCC21550 Hi,
I am designing a DC to AC inverter intended to drive an 2x ultrasonic load 40kHz, 60W. The gate driver UCC21550BQDWRQ1 is used for the switching; 400V DC at 50% cycle, 39kHz, with a transformer of 3.1 ratio to convert the 200V…
Part Number: UCC21550 Hi,
I am designing a high voltage Isolated half bridge with two transformers connected in parallel, see the attached figure below. Kindly support with the following questions.
1) Is it recommended to have a ground plane on section…
Part Number: UCC21550-Q1 Hello, Good day. Our customer tested ucc21550-q1 and found a negative voltage between out pin and Vss pin. When the negative voltage of the driver chip spikes, the negative voltage signal on the driver chip is 5V/ns. The driver…
Part Number: UCC21550-Q1 Other Parts Discussed in Thread: UCC21550 , UCC21551 Dear teams,
Rdt=1k is not within the range of the datasheet. Is there any other way to calculate DT at this time?
Thanks!
Part Number: UCC21550-Q1 Other Parts Discussed in Thread: UCC21551 Hi,
I am using this gate driver for an application and to design the power supply I require the quiescent current rating. I see the VDD quiescent current rating on the data sheet of this…
Part Number: UCC21550-Q1 Other Parts Discussed in Thread: UCC21551 Hi team.
Recently, we got a gate driver to replace their legacy solution NIS6622A. We promoted UCC21550-Q1 to compete.
Actually it’s an industrial application – Solar inverter. Is there…
Part Number: UCC21550-Q1 Could you please let me know the correct contact point to request about design related questions on UCC21550-Q1 device internally?
What is an IPT00 file? I would be happy to provide it, however I cant find any info online about it.
I have tried adding a resistor(everything from 1g to 1m) connecting between the two grounds but it hasn't changed anything. I have also tried adding resistors…
Hi Vignesh,
Thank you for following up and providing details.
It looks like this could be occurring at the higher current values in the PFC circuit?
CMTI is definitely an important spec. It looks like with the GaN FET, there definitely could be very fast…
