variable voltage gate driver recomindation

yefj · May 10, 2024

Hello,I have this good component which coould drive 4A its output floating voltage shown below.
The floating voltage is directly equals to its supply voltage.

However is there a gate driver just like this where the output could be tuned by some pin resistor connection?

Thanks.

In applications where we need adjustable gate drive voltage, we are using a variable voltage regulator for driver supply.

Hello FVM ,I have this configuration I used before.
My load Is not TGA2590 but the UCC5304 VDD supply VDD pin.
what current do i need to supply with this regulator according to UCC5304 ?
6A continues?
Thanks.

Gate driver draws only significant current during switching. Use sufficient bypass capacitor > 1 uF.
