SGM3200 Charge Pump Boost DC/DC Integrated Load Switch

GENERAL DESCRIPTION

The SGM3200 is a switched capacitor voltage converter that delivers a regulated output. No external inductor is required for operation. SGM3200 also integrates one 500mA load switch.

The SGM3200 can deliver up to 500mA 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 SGM3200 uses charge pump technique to provide a regulated output from a varying input supply. The SGM3200 contains a thermal management circuit to protect the device under high temperature conditions.

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