Other Parts Discussed in Thread: LMG3410-HB-EVM,
Dear team,
We are trying to cost down our GaN daughter cards to make our solution more competitive by changing isolated power supply on LMG3410-HB-EVM to bootstrap power supply.
When starting up, each low-side LMG3410 should be driven by a PWM with low duty cycle to charge up bootstrap cap of high-side LMG3410 and avoid inductor current saturation. High-side LMG3410 can't be switched correctly until corresponding fault signal set high.
So any clues on how we should modify the firmware of TIDM-1007 for bootstrap powered GaN daughter cards?
Thanks and Best Regards,
Charles Zhao
