In this moment, the peak current, IL

max flowing through the inductor and the driver Tr. is described as
follows:
IL

With the formula 4,6, and IL

L)...........................................................................Formula 8
Therefore, peak current is more than I
OUT
. Considering the value of IL
X
max, the condition of input and output,
and external components should be selected.
In the formula 7, peak current IL
X
max at discontinuous mode can be calculated. Put Iconst
=
0 in the formula.
The explanation above is based on the ideal calculation, and the loss caused by L
X
switch and external
components is not included. The actual maximum output current is between 50% and 80% of the calculation.
Especially, when the IL
X
is large, or V
IN
is low, the loss of V
IN
is generated with the on resistance of the switch. As
for V
OUT
, Vf (as much as 0.3V) of the diode should be considered.
