DESCRIPTION
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).
