Description

The TPS6040x family of devices generates 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 SOT-23 package, the complete

converter can be built on a 50-mm2 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.

TPS60400 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.
