   产品概述 返回TOPfpu嘉泰姆

The CXUS65140 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.fpu嘉泰姆

The CXUS65140 can deliver a maximum output current of 200mA with a typical conversion efficiency of greater than 80% over a wide output current range.fpu嘉泰姆

The CXUS65140 is available in SOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.fpu嘉泰姆
