The AX3001 is high efficiency synchronous PWM step-up DC/DC converters,optimized to provide a highefficient solution to medium power systems.The devices work under the input voltage between 0.9~4.4V with a 1.4MHz fixed frequency switching .These features minimize overall solution footprint by allowingthe use of tiny.Low profile inductors ceramic capacitors.Automatic PWM/PFM mode swiching at light load saves power and improve efficiency
