Part Number: LM5088
Tool/software: WEBENCH® Design Tools
I have created a design using WEBENCH using the LM5088.
Vin =14-32VDC
Vout = -20VDC
Iout max is 3.5ADC
The WEBENCH design states to use a 33uH inductor 2.65m ohms, I think this is too high of a inductor value.
it also select Freq ~170kHz
But when I use SLVA721A appnote calculations, I come in at ~ 10uH.
What am I missing???? I also have attached pdf file of Design to this.
