The PE2118 is high efficiency synchronous,
PWM 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 1.4MHz fixed frequency
switching. These features minimize overall
solution footprint by allowing the use of tiny,
low profile inductors and ceramic
The PE2118 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
The PE2118 regulators are available in the
industry standard SOT-23-6 power packages
(or upon request).
