 GENERAL DESCRIPTION

The AX5302 is high efficient PWM step up controll er. Designed to drive an external N-channel MOSFET Output voltage is programmable with 1.0V of standard voltage supply internal, and using externally connected com ponents, output voltage (FB) can be set up at will.

The AX5302 can be operated at switching frequencies of 500kHz allowing for easy filtering and low noise , the size of the external components can be reduced. An enable function and thermal shutdown functions are built inside. The soft start time can be programmed by outside capacitor; the function prevents overshoot at startup.
