The aim is to design a synchronous boost converter using a microcontroller ATMEGA 2560 switching at 31.25kHz

i tried turning on the high side switch with NOT gate signal from the low side PWM signal. High side mosfet turns on when the low side is turned off but the voltage remains at 4 volt and does not increase

What could be the cause of this problem?
