The values for the external components are
determined as follows:
Current limit input threshold, V
C
Peak current to load, I
Short circuit current, I
Low output voltage limit, V
High output voltage limit, V
Voltage sensing delay, t
SCR trigger power limiting resistor, R
S
is determined by the current loop dynamics
