SGM3204,PDF数据表下载

SGM3204 pdf资料下载The SGM3204 generates an unregulated negative output voltage from an input voltage ranging from 1.4V to 5.5V. The device is typically supplied by a pre-regulated supply rail of 5V or 3.3V. Due to its wide input voltage range, two or three NiCd, NiMH, or alkaline battery cells, as well as one Li-ion cell can also power them. Only three external capacitors are required to build a complete DC/DC charge pump inverter. Assembled in a 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 diode that is typically needed for start-up into load by integrated circuitry. The SGM3204 can deliver a maximum output current of 200mA with a typical conversion efficiency of greater than 80% over a wide output current range. SGM3204YN6G/TRDatasheet pdf资料数据表下载
