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

          The SGM3110 is a Micro-Power 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 total converter board area to a minimum in space-restricted applications.

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