3 Instructions

TPS6303x devices provide power

Solutions for products powered by two or two batteries

Three alkaline, NiCd or NiMH batteries, or one battery

Li-ion or Li-polymer battery. The output current can

600 mA on a single-cell Li-Ion battery

or Li-polymer battery, then discharge it to 2.5 V

or lower. Buck-boost converter based on

Fixed frequency, pulse width modulation (PWM)

The controller uses synchronous rectification to obtain

Maximum efficiency. At low load currents,

Converter enters power saving mode to remain high

efficiency over a wide load current range. Power saving

Modes can be disabled, forcing converters

Operates at a fixed switching frequency. maximum value

Average current in switches limited to typical values

The value is 1000 mA. The output voltage is

programmable using an external resistor divider, or

Internally fixed on the chip. The converter can be

Disable to minimize battery consumption. During shutdown,

The load is disconnected from the battery.

TPS6303x devices are free to run

The temperature range is –40°C to 85°C. device is

Packaged in a 10-pin VSON package in a 2.5-

mm x 2.5 mm (DSK).
