The TPS61252 device provides a power supply solution for products powered by either a
three-cell alkaline, NiCd or NiMH battery, or an one-cell Li-Ion or Li-polymer battery. The wide
input voltage range is ideal to power portable applications like mobile phones or
computer peripherals. The device has a resistor programmable
(RILIM) input current limit and is suitable for a wide variety of
applications.
During light loads, the device
automatically
enters skip mode (PFM), which allows the converter to maintain the
required output voltage, while only drawing 30 µA
quiescent current from the battery. This
allows maximum efficiency at lowest quiescent currents.
TPS61252 allows the use of small inductors and capacitors to achieve a small solution
size. The possibility to reduce the current limit by a external resistor offers the potential use
of physically even smaller inductors with lower rated
currents to further reduce total solution sizes of the power supply.
During shutdown, the load is completely disconnected from the battery. The TPS61252 is available in
a 8-pin
WSON package measuring 2 mm × 2 mm (DSG).
