The TPS60400QDBVRQ1 family of devices produces an unregulated negative output voltage from an input voltage of 1.8V to 5.25V. These devices are typically powered from pre-regulated 5V or 3.3V rails. Due to their wide input voltage range, two or three NiCd, NiMH or alkaline batteries, as well as a Li-Ion battery, can also power them.

The TPS60400QDBVRQ1 requires only three external 1µF capacitors to build a complete DC-DC charge pump inverter. The entire converter is housed in a 5-pin SOT-23 package and can be built on a 50mm2 board area. Replacing the Schottky diodes typically required to start a load with an integrated circuit can achieve additional board area and reduce component count.
