TPS63000DRCR

The TPS63000DRCR devices provide a power supply solution for products powered by either a two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery. Output currents can go as high as 1200 mA while using a single-cell Li-Ion or Li-Polymer Battery, and discharge it down to 2.5 V 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 the Power Save mode to maintain a 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 of TPS63000DRCR can be programmed by 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 completely disconnected from the battery.The TPS63000DRCR is packaged in a 10-pin QFN PowerPAD™package measuring 3 mm x 3 mm (DRC).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.TPS63000DRCR has limited built-in ESD protection. The leads should be shorted together or the TPS63000DRCR placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
