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.
