SGM3110

Regulated Charge Pump

GENERAL DESCRIPTION

FEATURES

The SGM3110 is a MicroPower switched capacitor

voltage converter that delivers a regulated output. No

external inductor is required for operation.

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

− Step-Up Voltage Converter

− Input Voltage Range:

SGM3110-5.0: 2.7 to 5.0V

SGM3110-4.5: 2.7 to 4.5V

− MicroPower Consumption: 60µA

− Fixed 5V, 4.5V ± 4% Output

− Peak Current 250mA for 100ms

− High Frequency 750kHz Operation

− Logic-Controlled Shutdown

− Short-Circuit/Over-Temperature Protection

− Lead (Pb) Free SOT23-6 Package

total converter board area to

space-restricted applications.

minimum in

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.

The SGM3110 has lead (Pb) free SOT23-6 package and is

rated over the -40°C to +85°C temperature range.
