External Bootstrap Diode
An external bootstrap diode may enhance the
efficiency of the regulator. The applicable
conditions of external BST diode are:
VOUT=5V or 3.3V; and
Duty cycle is high: D=
IN
OUT
V
>65%
In these cases, an external BST diode is
recommended from the output of the voltage
regulator to BST pin, as shown in Fig.2
