The TPS6040x family of devices produces an unregulated negative output voltage from an input voltage of 1.6V to 5.5V. These devices are usually supplied from a 5V or 3.3V pre-recorded power rail, and because of its wide input voltage range, two or three NiCd, NiMH or alkaline batteries, and a Li-Ion battery can also power them.

A complete DC-DC charge pump inverter requires only three external 1-F capacitors. Assembled in a 5-pin SOT-23 package, the complete converter can be built on a 50mm board area. Additional board area And the component count is reduced by replacing the Schottky diodes, which are typical IC loads required for startup.

Over a wide output current range, the TPS6040x has a maximum output current of 60 mA and a typical conversion efficiency greater than 90%. Three device options for 20 kHz, 50 kHz and 250 kHz fixed frequency operation are available. The TPS 60400 features a variable switching frequency to reduce operating current in large load range applications and enable the design of low value capacitors become possible.

Ceramic capacitors for input voltages up to 60 mA only require input voltages from 1.6V to 5.5V input voltage range for improved efficiency at low output currents (TPS 60400) Device quiescent current typical 65 A Integrated active Schottky diodes are used Start with the TPS60400EVM-178 available as an evaluation module in a small 5 Pin SOT-23 package.
