SGM3204 Unregulated 200mA Charge Pump Voltage Inverter GENERAL DESCRIPTION FEATURES The SGM3204 generates an unregulated negative output  Inverts Input Supply Voltage voltage from an input voltage ranging from 1.4V to 5.5V.  Up to 200mA Output Current The device is typically supplied by a pre-regulated supply  Input Voltage Range from 1.4V to 5.5V rail of 5V or 3.3V. Due to its wide input voltage range, two  Quiescent Current: 1.5mA (TYP) or three NiCd, NiMH, or alkaline battery cells, as well as  950kHz Switching Frequency  Integrated Active Schottky Diode for Start-Up into one Li-ion cell can also power them. Load Only three external capacitors are required to build a  -40℃ to +85℃ Operating Temperature Range complete DC/DC charge pump inverter. Assembled in a  Available in Green SOT-23-6 Package small package, the complete converter can be built on a 50mm2 board area. Additional board area and component count reduction is achieved by replacing the Schottky APPLICATIONS diode that is typically needed for start-up into load by integrated circuitry. LCD Bias GaAs Bias for RF Power Amps The SGM3204 can deliver a maximum output current of Sensor Supply in Portable Instruments 200mA with a typical conversion efficiency of greater than Bipolar Amplifier Supply 80% over a wide output current range. The SGM3204 is available in SOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
