| Abstract: | A comparator is designed in this article, whose threshold voltage is adjustable to load currents. This comparator is applied to sense the current flowing through the synchronous rectification used in the DC/DC switching power supply. It adjusts the threshold voltage according to the output feedback voltage to permit small amounts of reverse current to flow from the output during light loads in PWM mode. |

| Keywords: | comparators adjustable threshold voltage synchronous rectification reverse currents |
