SGM3110
Micro-Power Regulated Charge Pump
Micro-Power Regulated Charge Pump
GENERAL DESCRIPTION

The SGM3110 is a regulated switched-capacitor boost converter with low-power consumption. This device is characterized by very low quiescent current. There is no need to connect inductors outside the chip. The small package size makes the device very suitable for space limited applications.

Different input voltages can produce a regulated output voltage. It is capable of supplying 100mA output current.

SGM3110 has thermal shutdown function to protect the equipment under short-circuit conditions.

The SGM3110 is available in a Green SOT-23-6 package and is rated over the -40  to +85 temperature range.
