Hello,
Would you please let me know about how to design the switching frequency of
hysteretic mode converter; MP9486A ?
If I used VIN=60V, VOUT=5V, L=33uH, Iout=1 and if I assume K=0.8 on Equation (2)
of MP9486A data sheet, I would have Fsw = approx.174KHz.
It seems close to data sheet page 7 waveform ( Cout=100uF、stady state Iout=1A: T=around
5.6us)
Is above correct ?
If I want to increase Iout from 1A to 2A, and if I want same Fsw,
I should decrease K from 0.8 to 0.4 by increasing Cout from 100uF to any value?
( I don’t have EVB now in addition to simulation model)
Best Regards
