3 Description
The TPS6040x-Q1 family of devices generate an unregulated negative output voltage from an input voltage ranging from 1.8 V to 5.25 V. The devices are typically supplied by a preregulated supply rail of 5 V or 3.3 V. Due to its wide-input voltage range, two or three Ni Cd, Ni MH, or alkaline battery cells, as well as one Li-Ion cell, can also power them.
Only three external 1-μF capacitors are required to build a plete DC-DC charge pump inverter. Assembled in a 5-pin SOT-23 package, the plete converter can be built on a 50-mm2 board area. Replacing the Schottky diode typically needed for start-up into load with integrated circuitry can achieve additional board area and ponent count...
