ing cycle. The secondary function of the RON resistor is to
create a nearly constant operating frequency over the input
operating voltage range. If the output voltage of the regulator
is changed by adjusting the feedback divider then it is gener-
ally required that the RON resistor value also be changed in
order to maintain the same operating frequency.
Cout A parallel connection of a 1uF 50V and a 100uF 6.3V
multilayer ceramic are used for the output capacitor. Loca-
