The TPS63060 provides a power supply solution for products powered by either three-cell
up to six-cell alkaline, NiCd or NiMH battery, or a one-cell or dual-cell Li-Ion or Li-polymer
battery. Output currents can go as high as 2A while using a dual-cell Li-Ion or Li-Polymer Battery,
and discharge it down to 5V 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 2.25A. The output voltage is programmable using an external resistor divider, or
is fixed internally on the chip. 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 SON
PowerPAD package measuring 3mm × 3mm (DSC).
