Hi all,
Very new at designing switching power supplies so please be kind !
I am using the spreadsheet http://www.onsemi.com/PowerSolutions/supportDoc.do?type=tools&category=981
NCL1608 Design Worksheet.
When I put in Target Output Voltage Vout=155 (which is the voltage I want out of the curcuit.
It gives
MAX Calculated Inductor Value L(MAX)_C =-11450
Can you please explain why this is a negative value ?
