METHOD TO MAINTAIN SYNCHRONOUS RECTIFICATION AT LIGHT LOADS

An electronic device (100) includes a synchronous rectifier (104) and a battery (102). The synchronous rectifier (104) outputs a charging current (I) to the battery (102). The electronic device (100) includes a rectifier controller (108) that adjusts a resistance of a switch (110) of the rectifier (104) based on a magnitude of the charging current (I).
