Hello,I have built a DC/DC synchronous boost converter, to do this i use two mosfet and to control this one, I use a TPS28225 driver.But the system don't work, the low side mosfet switch well but the high side don't work, we haven't signal on UGATE port.I don't understand the problem, if you have a solution for me i will be happy.thank you in advance
I think that both Q3 and D7 are inverted. Look carefully at the circuit application on the datasheet, one-phase POL regulator.
I don't understand what do you mean ?This is a syncronous boost topology and I use a mosfet transistor N channel thus I think the power components are in a good place.I have replace the mosfet by a diode and mosfet to improve the efficiency.
