YB1300S
Switched Capacitor Boost Converter 5V/4.5V
Description
The YB1300S is a switched capacitor
DC/DC boost converter that produces a
regulated 5V output. The input voltage
range is from 2.7V to 5.0V that makes the
YB1300S ideally for a single cell Li-Ion
battery source.
The YB1300S works well for step-up
applications without the need for an
inductor. The 1MHz switching frequency
allows the use of small SMD capacitors.
The YB1300S provides thermal protection,
short-circuit current limit protection. In order
to prevent in-rush current effectively, it
provides
automatic
soft-start.
The
shutdown current is less than 0.1μA. The
YB1300S is available in a 6-pin SOT23
package.
