DESCRIPTION
The TPS6303x 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 600 mA while using a single-cell Li-Ion
or Li-Polymer Battery, and discharge it down to 2.5V
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 1000 mA. 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 QFN PowerPAD™ package
measuring 2.5mm × 2.5 mm (DSK).
