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.
