Other Parts Discussed in Thread: LMG1210, LMG1020
Hi, I'm working on wireless power transfer system.
We are using GaN device (EPC 2111) and its input capacitance is almost 250p F.
I'm looking for a buffer or driver that can be used right after our high side driver to drive our target GaN device.
Output of our high side driver swings 0~20V with the bootstrap voltage(VBOOT) and floating node(VSW) that are swing 5~20V and 0~15V for each.
Voltage difference between VBOOT and VSW is 5V and a cap are between them.
PWM input signal will be 6.78MHz, therefore, I need a buffer or driver that can operated in 6.78MHz.
I found UCC27200 device can accept the output of my circuit as an input, but I couldn't find the maximum frequency range it can operate.
Can it be used in the 6.78MHz system?
I want to use another high side driver, but we need to keep our design in use.
If there's any other suggestion of devices, please tell me.
Thank you for your precious time to read my issue.
