Description
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 8pin WSON package measuring 2 mm × 2 mm (DSG).
