Application
Description
The XA3106 is high efficiency, fixed frequency,
Buck-Boost DC/DC converters which operates
from input voltages above, below or equal to the
output voltage. The devices are suitable for
single lithium-ion, multicell alkaline or NiMH
applications where the output voltage is within
the battery voltage range.
The switching frequencies up to 1.5 MHz could
be fixed by employing an external resistor, and
the oscillator could be synchronized to an
external clock. the quiescent current is 1mA,
and this feature maximizing the battery life in
portable applications.
Other features include a 1 µA shutdown,
soft-start control, thermal shutdown and current
limit. The XA3106 converters are available in
the 10-pin thermally enhanced MSOP packages
(or upon request).
