Product Summary

The TPS60400DBVR is a unregulated charge pump voltage inverter that generates an unregulated negative output voltage from an input voltage ranging from 1.6 V to 5.5 V. The device is typically supplied by a preregulated supply rail of 5 V or 3.3 V. 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. The applications of the TPS60400DBVR include LCD Bias, GaAs Bias for RF Power Amps, Sensor Supply in Portable Instruments, Bipolar Amplifier Supply, Medical Instruments, Battery-Operated Equipment.
