YB1300

Regulated Charge Pump 5V 100mA

Description

Features

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.

Switched-Capacitor Step-Up

Operation

Input Range : 2.7V to 5.0V

Output Voltage : 5V

Output Current : 2.7V≦VIN＜3.2V,

OUT≦30mA

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.

Output Current :3.2V≦VIN＜5V,

OUT≦100mA
