8.2.2.4 Output Diode

The voltage stress by the converter on the diode can be found with Equation 20.

Equation 20. V D i o d e S t r e s s = V o u t + V i n M A X N p s
Equation 21. V D i o d e S t r e s s =5   V + 40   V 3 .33 =17   V

Note that any diode picked should have a voltage rating of well above this value as it does not include parasitic spikes in the equation. The UC1843B-SP diode was picked to have a voltage rating of 60 V.
