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

capacitors.

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

output.

The PE2118 regulators are available in the

industry standard SOT-23-6 power packages

(or upon request).
