SLVS653A – JUNE 2008 – REVISED AUGUST 2009 HIGHLY EFFICIENT, SINGLE INDUCTOR BUCK-BOOST CONVERTER WITH 2-A SWITCHES • Up to 96% Efficiency • 1200-mA Output Current at 3.3 V in Step Down The TPS6301x devices provide a power supply solution for products powered by either a two-cell or Mode (VIN = 3.6 V to 5.5 V) three-cell alkaline, NiCd or NiMH battery, or a • Up to 800-mA Output Current at 3.3 V in Boost one-cell Li-Ion or Li-polymer battery. Output currents Mode (VIN > 2.4 V) can go as high as 1200 mA while using a single-cell • Automatic Transition between Step Down and Li-Ion or Li-Polymer Battery, and discharge it down to Boost Mode 2.5 V or lower. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) • Device Quiescent Current less than 50µA controller using synchronous rectification to obtain • Input Voltage Range: 2 V to 5.5 V maximum efficiency. At low load currents, the • Fixed and Adjustable Output Voltage Options converter enters Power Save mode to maintain high from 1.2 V to 5.5 V efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to • Power Save Mode for Improved Efficiency at operate at a fixed switching frequency. The maximum Low Output Power average current in the switches is limited to a typical • Forced Fixed Frequency Operation and value of 2200 mA. The output voltage is Synchronization possible programmable using an external resistor divider, or is • Load Disconnect During Shutdown fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, • Output Overvoltage Protection the load is disconnected from the battery. The device • Overtemperature Protection is packaged in a 20-pin WCSP package measuring • Available in Small 20 pin 2.14 mm x 1.93 mm, 2.14 mm x 1.93 mm (YFF). WCSP Package Typical Application Circuit • All Two-Cell and Three-Cell Alkaline, NiCd or NiMH or Single-Cell Li Battery Powered Products • Portable Audio Players • PDAs • Cellular Phones • Personal Medical Products • White LEDs 1 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.
