YB1300
Regulated Charge Pump 5V 100mA
Description
The YB1300 is a switched capacitor DC/DC
step up converter that produces a regulated
5V output. The input voltage range is from
2.7V to 5.0V that makes the YB1300 ideally
for a single cell Li-Ion battery source.
The YB1300 works well for step-up applica-
tions without the need for an inductor. The
1MHz switching frequency allows the use
of small SMD capacitors. The YB1300
provides thermal protection, short-circuit
current limit protection. In order to prevent
in-rush current effectively, it provides
automatic soft-start. The quiescent current
is 30µA without load and its shutdown
current is less than 0.1µA. The YB1300 is
available in a 6-pin SOT23 package.
