The 1st difference input step which receives the input potential which is close to the wide area entry

摘要

In execution form, the switch mode power source which operates at the switching frequency which is higher than 10MHz (SMPS) and also, the new analog - digital converter (ADC) architecture can be used. Analog - digital converter execution form, very low electricity consumption, short conversion time is achievable, is actualization possible with the simple hardware. As for another advantage of should observe, as for a certain ADC execution form, the non-linear profit quality which offers the load transient response which is improved to the digital controller is had.
