AX5301-PWM Step-up Controller DataSheet

GENERAL DESCRIPTION
    The AX5301 is high efficient PWM step-up controller. Designed to drive an external N-channel MOSFET, 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 AX5301 can be operated at switching frequencies of 500kHz allowing for easy filtering and low noise, the size of the external components can be reduced.
This controller also contains an error amplifier circuit as well as a soft-start circuit
that prevents inrush-current at startup. An enable function and thermal shutdown
functions are built inside.
