TPS63060DSCT

The TPS63060DSCT is a high input voltage Buck-boost Converter with 2A switch. The TPS6306x device provides a power supply solution for products powered by either three-cell up to six-cell alkaline, NiCd/NiMH battery or one-cell/dual-cell Li-ion/Li-polymer battery. Output currents can go as high as 2A while using a dual-cell Li-ion/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 current, 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.
