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 for 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 will automatically enter skip mode (PFM), which allows the converter to maintain the required output voltage, while only drawing 30 mA from the battery. This will allow maximum efficiency at lowest quiescent currents.
