Step-up PWM DC/DC Converter APE1901 ™ GENERAL DESCRIPTION The APE1901 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 APE1901 can be operated at switching frequencies of 500kHz 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.
This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents inrush-curre...
