Recommended Diodes
Schottky Diode Selection
The selection of the external diode depends on the application.
If IOUT is very low most of the time, and VOUT is high, select a
diode with a low reverse current for best efficiency. For lower
VOUT and higher IOUT, select a diode with a lower V_FORWARD and
R_FORWARD.
