AX5203 - Step-up PWM DC/DC Converter
The AX5203 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 AX5203 can be operated at switching frequencies of 500 kHz allowing for easy filtering and low noise, the size of the external
