AX5103A Step-up PWM DC/DC Converter ™ GENERAL DESCRIPTION The AX5103A is high efficient step-up DC/DC converter. Large output current is possible having a built in internal N channel MOSFET, and using an external coil and diode. The AX5103A can be operated at switching frequencies of 500kHz 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. This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents inrush-current at startup. The thermal shutdown function is built inside. ™ FEATURES Input voltage: 3.6V to 23V Output voltage: 4.0 V to 58V (±2.
