description

The TPS6040x is a family of devices that generate an unregulated negative output voltage from an input voltage

ranging from 1.6 V to 5.5 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 NiCd, NiMH, 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 complete dc/dc charge pump inverter. Assembled

in a 5-pin SOT23 package, the complete converter can be built on a 50-mm 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.

The TPS6040x can deliver a maximum output current of 60 mA with a typical conversion efficiency of greater

than 90% over a wide output current range. Three device options with 20-kHz, 50-kHz, and 250-kHz fixed

frequency operation are available. One device comes with a variable switching frequency to reduce operating

current in applications with a wide load range and enables the design with low-value capacitors.
