Original Question: LT3439 Power Dissipation Calculation by KenW
I am unclear on a couple terms in the Power Dissipation equations on page 8 of the datasheet.
a) What is Vsat in Pvsat equation?
b) What is V in Psw equation?
Verified Answer: RE: LT3439 Power Dissipation Calculation by Mikee_Lacson_00
a) Vsat can be taken form this graph
b) V is the switching node voltage. Vin can be used in this case
