Datasheet Summary
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 ponents can be reduced. Output voltage is programmable with 1.0V of standard voltage supply internal, and using externally connected ponents, 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...
