Part Number:LM26420
Tool/software: WEBENCH® Design Tools
I trying to simulate Webench below condition,
--------------------------------
・Device： LM26420X（fsw： 2.2MHz）
・Vin： 4～5.5V
・Vout1： 1.2V / 1.1A
・Vout2： 3.3V / 0.6A
--------------------------------
But, for example, Vout2(3.3V) inductor's Lowerbound is 7.988μH, I feel that more small inductance is no problem.
What is the reason for inductor's Lowerbound: 7.988μH?
(Is this Webench bug?)
By the way; I hope to use 3.3μH inductor, and compensation was over 45° in the condition of 3.3μH.
Is there any problem for 3.3μH?
