Notes
*1
Although the IC starts step-up operations from a V
DD
of 0.8V, the output voltage and oscillation frequency are stabilized at
V
DD
≥
1.8V or (Vref applied voltage + 0.7V). Therefore, a V
DD
of more than 1.8V or (Vref applied voltage + 0.7V) is recommended when
V
DD
is supplied from V
IN
or other power sources.

When obtaining V
DD
from a source other than V
OUT
, please
insert a capacitor C
DD
between the V
DD
pin and the GND pin in
order to provide stabler operations.
Please wire CL & C
IN
between the V
OUT
/V
DD
pin and the GND
pin. Strengthen the wiring sufficiently. When using a capacitor
other than ceramic or low ESR at CL, please take away
R
SENSE
and short.
Insert Rb and CB when using a
bipolar NPN Transistor.
