sgm 3110 micro - power regulated charge pump sg micro corp www.sg- micro.com march 201 8 C rev. a. 3 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 green sot - 23- 6 package and is rated over the - 40 to +85 temperature range. features step - up voltage converter input voltage range: SGM3110 - 5.0: 2.7v to 5.0v SGM3110 - 4.5: 2.7v to 4.5v micro - power consumption: 60a 4.5v and 5v regulated 4 % output voltages 250ma peak current for 100ms high frequency 750khz operation logic - controlled shutdown short - circuit and over - temperature protection s available in green sot - 23- 6 package applications cellular phones digital cameras handheld electronics led/display backlight driver leds for camera flash portable communication devices mp3 players gps receivers pdas typical application SGM3110 v out gnd shdn c- c+ v in c out 10f c in 10f v out v in c fly 1f on/off a ll data sheet.com
