Product Summary

The SGM3122 is a MicroPower switched capacitor voltage converter that delivers a regulated output. No external inductor is required for operation. The SGM3122 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 SGM3122 applications are: (1)Cellular Phones; (2)Digital Cameras; (3)Handheld Electronics; (4)LED/Display Backlight Driver; (5)LEDs for Camera Flash; (6)Portable Communication Devices; (7)MP3 Players; (8)GPS Receivers; (9)PDAs.
