GENERAL DEscriptION

The SGM3200 is a regulated switched-capacitor boost converter with low-power consumption. This device is characterized by very low 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 500mA output current. A 500mA current limit load switch is integrated in the SGM3200.

SGM3200 has thermal shutdown function to protect the e under short-circuit conditions.

The SGM3200 is available in a Green TDFN-3×3-8L package and is rated over the -40℃ to +85℃ temperature range.
