The TPS63000 devices provide a power supply solution for products powered by either a two-cell or three-cell
alkaline, NiCd or NiMH battery, or a one-cell Li-Ion or Li-polymer battery. Output currents can go as high as 1200
mA while using a single-cell Li-Ion or Li-Polymer battery, and discharge it down to 2.5 V or lower. The buck-boost
converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification
to obtain maximum efficiency. At low load currents, the converter enters Power Save mode to maintain high
efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to
operate at a fixed switching frequency. The maximum average current in the switches is limited to a typical value
of 1800 mA. The output voltage is programmable using an external resistor divider. The converter can be
disabled to minimize battery drain. During shutdown, the load is disconnected from the battery. The device is
packaged in a 10-pin QFN PowerPAD package measuring 3 mm × 3 mm (DRC).
