1 / 27 page TPS61097-33 V 0.9 V to 3.3V IN VOUT EN L GND VIN L1 C1 C2 V +3.3V OUT TPS61097 www.ti.com SLVS872C – JUNE 2009 – REVISED DECEMBER 2011 LOW INPUT VOLTAGE SYNCHRONOUS BOOST CONVERTER WITH LOW QUIESCENT CURRENT Check for Samples: TPS61097 1 FEATURES • Up to 95% Efficiency at Typical Operating APPLICATIONS Conditions • MSP430 Applications • Connection from Battery to Load via Bypass • All Single-Cell, Two-Cell, and Three-Cell Switch in Shutdown Mode Alkaline, NiCd, NiMH, or Single-Cell Li-Battery • Typical Shutdown Current Less Than 5 nA Powered Products • Typical Quiescent Current Less Than 5 μA • Personal Medical Products • Operating Input Voltage Range • Fuel Cell and Solar Cell Powered Products From 0.9 V to 5.5 V • PDAs • Power-Save Mode for Improved Efficiency at • Mobile Applications Low Output Power • White LEDs • Overtemperature Protection • Small 2.8-mm x 2.9-mm 5-Pin SOT-23 Package (6-Pin for Adjustable) DESCRIPTION The TPS61097 provide a power supply solution for products powered by either a single-cell, two-cell, or three-cell alkaline, NiCd, or NiMH, or one-cell Li-Ion or Li-polymer battery. They can also be used in fuel cell or solar cell powered devices where the capability of handling low input voltages is essential. Possible output currents depend on the input-to-output voltage ratio. The devices provides output currents up to 100 mA at a 3.3-V output while using a single-cell Li-Ion or Li-Polymer battery. The boost converter is based on a current-mode controller using synchronous rectification to obtain maximum efficiency. The maximum average input current is limited to a value of 350 mA. The output voltage can be programmed by an external resistor divider, or it is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the battery is connected to the load to enable battery backup of critical functions on the load. The fixed output device is packaged in a 5-pin SOT-23 package (DBV) measuring 2.8 mm × 2.9 mm. 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.
