Texas Instruments tps61096A

Description

The TPS61096A is a high output voltage boostconverter with ultra-low quiescent current. It isdesigned for products that require high efficiency atlight load conditions powered by either two-cellalkaline, or one-cell Li-Ion or Li-polymer battery.The TPS61096A integrates a 30-V power switch anda power diode. It can output up to 28 Volts. TheTPS61096A uses a PFM peak current controlscheme to obtain the highest efficiency over a widerange of input and output load conditions. It onlyconsumes 1 μA quiescent current and can achieve upto 70% efficiency under 10-μA load condition.The TPS61096A can also support selective inductorpeak current. With 250-mA current limit, theTPS61096A can reduce inductor ripple so that itreduces external component size for light loadapplications. With 500 mA current limit, theTPS61096A can provide 30 mA output current for aconversion from 3.3 V to 18 V.The TPS61096A integrates two-channel low-powerlevel shifters to convert low level signals to outputvoltage level signals for specific applications. It onlyconsumes 1-μA static current per channel andensures very low static and dynamic powerconsumption across the entire output range.The TPS61096A is available in a 12-pin 3.0-mm x2.0-mm WSON Package.
