Hello can you help us, we have some trouble around the functionning of the driver ADUM4221-1ARIZ !
This is our schematics we are actually using this driver with max duty of 90% of our PWM (30Khz), but we want to go to 100% of our PWM but we know that is we use a bootstrap it's not possible. So we decided to remove the bootstrap and add two DC/DC one for the High side (gnd_A) and the other one for the High side (gnd_b) and one for the two low side, but when we test this new functionnality the driver burn. Do you have some idea why our new functionnality was not working well !
Thanks you a lot
