Calculating the voltage difference between a switching pin out and a constant Vout

Sorry to trouble you all with a similar question. But this is a different question altogether regarding calculation of voltage difference. I am using NCV3063 IC.

According to my design of the boost converter in my board, I am measuring the values of pin1 and pin2 in multimeter and scope respectively. This is a reference board.

For Vin(Vcc) of 16V, The voltage at pin1(SWC) of the IC is 5.05V as measured in DMM.

1. Pin2 (SWE), I am measuring in scope, I am getting a peak-peak of some 15.8V with 30.6% duty and max amplitude of 13.8V.
2. Now, Vswce=difference between the pins 1 and 2.

How to calculate the voltage difference between (1) and(2)?

Or in general, how to calculate the voltage difference between a switching Vout pin (here, pin2) and a constant Vout pin (here, pin1).

Thanks

• You should include the schematic of your boost converter. Jan 29 '19 at 14:33
• As pointed out in comments provide a schematic this can probably be taken from the IC data sheet or application note. Also provide links to the data sheet and if applicable application note. Jan 29 '19 at 15:17
