Substitute the following conditions in formula 2.
Supply voltage V
IN
=
3.0~4.3 (V)
Output-side capacitor C2
=
1 (

Where it is assumed that,
VfLED
=
16 (V), Vf schottky
=
0.3 (V), R_sens
=
1.8 (

o
=
20 (mA), K
=
1.1
VfLED: LED Vf
Vf schottky: schottky diode Vf
R_sens: setting resistance
I

: set current
K: margin

Thus, 48.1 (
μ
H) is selected when the input voltage is low, 3.0 V.
Note that the calculation does not consider fluctuations in inductance. Toshiba recommend selection of an
inductance of 1.2 times the calculated value.
The recommended inductance under the above conditions is L (
