hai,
I am in the process of designing a pcb for driving my pushpull configuration having mosfets on the two coils of the push pull transformer driven by gate driver ic.In the last version of my design, during testing stage i happen to see that ,when my controller starts switching the gates using drivers, when large current flow through the coils of the transformer ,the noise level tends to rise to a large extend.What are the possible ways by which i can reduce such an effect in my design? In previous version i happen just to use a 5v ldo for powering it.but in this version i have changed my design to TPS5401 ic to buck to a 5v power supply enough to power my MCU.looking at scenario do you think i need to implement any other circuitry in my design to reduce such noise levels affecting my power supply? Should i move on with the current buck converter ic chosen for design?Will it withstand such switching noise in first hand?
