[Outline]
Output voltage compensation for USB power supply. Support it that the compensation the output voltage to descend by cable resistance and satisfies a USB standard. In addition, its feature of synchronous rectification reduces both the number of components used in the corresponding device and the mounting area.
To prevent interfere with the AM-band, it is equipped with the variable function that operates according to an external resistor and the external synchronization for the switching frequency.
