Re: Odd behaviour when attempting to simulate an LTC3633 switching regulator.


 

I do not understand how a 1uH can be too large.? according to the formula provided in the datasheet (for an output current ripple of ~40):

l=(vout/(f*ripple curent))*(1-(vout/vin))
l=(1.1/(4*0.039))*(1-(1.1/12))
l=6.39uH

Can anyone shed some light on this?
