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.
The kB3429 is capable of supplying an
output voltage between 2.5V and 4.3V, the
internal synchronous switch is desired to
provide high efficiency without Schottky.
The devices also featured providing up to
260mA from a single AA cell input or up to
600mA from a 2-cell AA with a 3V/3.3V
output.
The kB3429 regulators are available in
the industry standard SOT-23-6 power
packages (or upon request).
