Description
The
kB3429
is
high
efficiency
synchronous, step-up DC/DC converters
optimized to provide a high efficient solution
to medium power systems. The devices
work under the input voltage between 0.6V
and 4.4V with a 1.5MHz fixed frequency
switching. These features minimizes overall
solution footprint by allowing the use of tiny,
low
profile
inductors
and
ceramic
capacitors.
