TPS60403DBVR Description
The TPS60403DBVR is from the TPS6040x family and generates an unregulated negative output voltage from an input voltage ranging from 1.6 V to 5.5 V. The TPS60403DBVR is typically supplied by a pre-regulated 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.
