I am using this IC in boost converter configuration : boost converter
It steps up the voltage from 16.5V to 23V.
It drives a load current of 270mA.
I need to calculate the input current of the converter.
I understand that output power/input power is efficiency.
Since I know the output power, can I take the efficiency value from the graph 21 of the attached datasheet (86.8% approx - obtained from fig 21 graph) and find the input power?
With the input power, and since I know the input voltage, I can calculate the input current.
Is this the right way?
And I want to check if all the components at the output of the IC are properly rated.
Which parameters and components should I check and how to check?
Sorry for the poor image quality. The two transistors are taken from the SWE pin.
