Through Mode The voltage range is optimized for single-cell portable • Wide VIN Range From 2.3V to 4.8V applications like in smart-phones or tablet PCs. • IOUT ≥ 4A (Peak) at VOUT = 3.35V, VIN ≥ 2.65V Used as a high-power pre-regulator, the TPS6128x extends the battery run-time and overcomes input • Integrated Pass-Through Mode (35m Ω) current- and voltage limitations of the powered • Programmable Valley Inductor Current Limit system. and Output Voltage While in shutdown, the TPS6128x operates in a true • True Pass-Through Mode During Shutdown pass-through mode with only 2µA quiescent • Best-in-Class Line and Load Transient consumption for longest battery shelf life. • Low-Ripple Light-Load PFM Mode During operation, when the battery is at a good state- • In-Situ Customization with On-Chip E2PROM of-charge, a low-ohmic, high-efficient integrated pass- (Write Protect) through path connects the battery to the powered • Two Interface Options: system. – I2C Compatible I/F up to 3.4Mbps If the battery gets to a lower state of charge and its (TPS61280) voltage becomes lower than the desired minimum system voltage, the device seamlessly transits into – Simple I/O Logic Control Interface boost mode to utilize the full battery capacity. (TPS6128x) TPS6128x device supports more than 4A pulsed load • Thermal Shutdown and Overload Protection current even from a deeply discharged battery. In this • Total Solution Size <20mm2, Sub 1-mm Profile mode of operation, the TPS6128x enables the utilization of the full battery capacity: A high battery- cut-off voltage originated by powered components APPLICATIONS with a high minimum input voltage is overcome; new • Single-Cell Ni-Rich, Si-Anode, Li-Ion, LiFePO4 battery chemistries can be fully discharged; high Smart-Phones or Tablet PCs current pulses forcing the system into shutdown are • 2.5G/3G/4G Mini-Module Data Cards buffered by the device seamlessly transitioning between boost and by-pass mode back and forth. • Current Limited Applications Featuring High Peak Power Loads This has significant impact on the battery on-time and translates into either a longer use-time and better user-experience at an equal battery capacity or into reduced battery costs at similar use-times. The TPS6128x operates in synchronous, 2.3MHz boost mode and enters power-save mode operation (PFM) at light load currents to maintain high efficiency over the entire load current range. The TPS6128x offers a very small solution size (<20mm2) due to minimum amount of external components, enabling the use of small inductors and input capacitors, available as a 16-pin chip-scale package (CSP). 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. 2 I2C is a trademark of NXP Semiconductors.
