AX5201 Step-up PWM DC/DC Converter GENERAL DESCRIPTION The AX5201 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 AX5201 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. FEATURES - Input voltage3V to 20V - Output voltage3.3V to 32V - Duty ratio0% to 85% PWM control - Oscillation frequency500KHz. - Enable and Thermal Shutdown function. - Internal Current limit. - Built-in N-channel MOSFET - SOP-8L with Exposed pad Pb-Free package.
