The KF6400 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 minimizes overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.

The KF6400 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 KF6400 regulators are available in the industry standard SOT-23-6 power packages (or upon request).
