TPS63002DRCT Datasheet PDF - TI

The TPS63002DRCT is a Buck-boost Converter provides a power supply solution for products powered by either a two-cell or three-cell alkaline, NiCd or NiMH battery or one-cell li-ion or li-polymer battery. Output currents can go as high as 1200mA 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 1800 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.
