NEW PRODUCT BULLETIN TPS63030/31 95% Efficient, 0.8A Buck-Boost DC/DC Converter in 2.5x2.5mm2 QFN DESCRIPTION The TPS6303x series is a family of synchronous BuckBoost DC/DC Converters that are ideally suited for applications powered from 1-cell Li-Ion/Li-Polymer battery or 2-/3-cell Alkaline/NiCd or NiMH batteries. ADDITIONAL SPECIFICATIONS * Synchronizable to External Clock Signal * Automatic Transition between Buck/Boost Mode DEVICE OPTIONS With its wide input voltage range starting at 1.8V up to 5.5V, the TPS6303x series can support future battery technologies with ultra-low battery discharge cycles. Featuring automatic transition between buck and boost mode, the device can provide up to 800mA output current in buck mode @ 3.3V or up to 500mA output current in boost mode @ 3.3V. The TPS6303x is based on a fixed frequency, pulsewidth-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency, up to 96%.

QUICK COMPARISON TO COMPETITION AND OTHER TI PRODUCTS Product Positioning within TI Portfolio TPS6303x with 0.8A output current is the extending TIs Buck/Boost DC/DC Converter series for lower current levels, comparing to the 1.2A output current TPS6300x series. Product Positioning within Market & Key Selling Points * Main competition is LTC with a series of 2 Buck-Boost DC/DC Converter called LTC344x. They are very similar to each other; the main difference is the output current and therefore the inductor size. * ADI is entering the market with new Buck/Boost devices; they are not released as of October 2008. * Compared to TIs TPS63030, each competing device has certain drawbacks in output current, voltage range, quiescent current or package/inductor size, and none can reach TI's high efficiency curve over the input range. The TPS6303x offers an overall unique combination of features, starting at the highest output current with smallest inductor, which contributes to the smallest solution size. A wide input range (starting as low as 1.8V) and unique efficiency curve over the wide battery voltage range make the TPS63030 to the leader in the Buck-Boost DC/DC converter market.
