AX5202  Step-up PWM DC/DC Converter

性能描述：
     The AX5202 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 anddiode.
     The AX5202 can be operated at switching frequencies of 500 kHz 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 soft-start time can be programmed by outside capacitor; the function prevents overshoot at startup. Build inside Current limit, Thermal Shutdown and enable functions.

特点：
•  Input voltage：3V to 16V
•  Output voltage：3.3V to 23V
•  Duty ratio：0% to 85% PWM control
•  Oscillation frequency：500KHz.
•  Enable and Thermal Shutdown function.
•  Internal Current limit.
•  Built-in N-channel MOSFET
•  SOP-8L with Exposed pad Pb-Free package.
