Hello,
I would like to increase the BOOT resister for reducing the spike noise.
Could you please let me know acceptable maximum resistance value or calculation for deciding the boot resistance?
I understood that efficiency will be decreased when we increase the boot resistance.
However our customer would like to reduce the spike noise by expense of efficiency.
Customer requirement.
Vin: 12V, Vout 0.9V, Iout: 15A, Fsw:970kHz,
Boot resistance is 2Ω now.
Also our customer use Snubber RC: 1Ω+1000pF.
Best Regards,
Ryuji Asaka
