3 Description
The TPS61096A is a high output voltage boost
converter with ultra-low quiescent current. It is
designed for products that require high efficiency at
light load conditions powered by either two-cell
alkaline, or one-cell Li-Ion or Li-polymer battery.
The TPS61096A integrates a 30-V power switch and
a power diode. It can output up to 28 Volts. The
TPS61096A uses a PFM peak current control
scheme to obtain the highest efficiency over a wide
range of input and output load conditions. It only
consumes 1 µA quiescent current and can achieve up
to 70% efficiency under 10-µA load condition.
The TPS61096A can also support selective inductor
peak current. With 250-mA current limit, the
TPS61096A can reduce inductor ripple so that it
reduces external component size for light load
applications. With 500 mA current limit, the
TPS61096A can provide 30 mA output current for a
conversion from 3.3 V to 18 V.
The TPS61096A integrates two-channel low-power
level shifters to convert low level signals to output
voltage level signals for specific applications. It only
consumes 1-µA static current per channel and
ensures very low static and dynamic power
consumption across the entire output range.
The TPS61096A is available in a 12-pin 3.0-mm x
2.0-mm WSON Package.
