AX5104 Step-up PWM DC/DC Converter  GENERAL DESCRIPTION The AX5104 is high efficient step-up DC/DC converter. Large output current is possible having a built in internal transistor, and using an external coil and diode. The converter can be operated at switching frequencies of 800KHz allowing for easy filtering and low noise, the size of the external components can be reduced. Output voltage is programmable with 1.0V of standard voltage supply internal, and using externally connected components, output voltage (FB) can be set up at will. The AX5104 is external soft-start function that prevents inrush-current and overshooting at startup, soft-start time is be set up by outside capacitance.
