Abstract
The invention provides a multi-function active circuit of PWM chip. By compensating for the input voltage, improving the path of voltage brownout detection, and switching the current route of the high voltage terminal to a current detection circuit and a linear compensator through an electrical switch, the multi-function active circuit has only one terminal connected to the high voltage terminal but still has multiple functions, such that the power consumption of the activation circuit can be minimized.
