SGM3110

Micro-Power Regulated Charge Pump

GENERAL DESCRIPTION

FEATURES

The SGM3110 is a Micro-Power switched capacitor

voltage converter that delivers a regulated output. No

external inductor is required for operation.

● Step-Up Voltage Converter

● Input Voltage Range:

SGM3110-5.0: 2.7V to 5.0V

SGM3110-4.5: 2.7V to 4.5V

The SGM3110 can deliver up to 100mA to the voltage

regulated output. It features very low quiescent current

and high efficiency over a large portion of its load range,

making this device ideal for battery-powered

applications. Furthermore, the combination of few

external components and small package size keeps the

total converter board area to a minimum in space-

restricted applications.

● Micro-Power Consumption: 60µA

● 4.5V and 5V Regulated ±4% Output Voltages

● 250mA Peak Current for 100ms

● High Frequency 750kHz Operation

● Logic-Controlled Shutdown

● Short-Circuit and Over-Temperature Protections

● Available in Green SOT-23-6 Package

The SGM3110 uses a pulse skipping technique to

provide a regulated output from a varying input supply.

The SGM3110 contains a thermal management circuit

to protect the device under continuous output short-

circuit conditions.

APPLICATIONS

Cellular Phones

Digital Cameras
