Abstract
Provided is a current sensing signal comparing device and current sensing signal comparing method. The current sensing signal comparing device includes a current sensing circuit for detecting a current signal of a switching circuit and thereby generating a current sensing signal, a control unit for outputting a control signal, and a compensating circuit for compensating the current sensing signal according to the control signal. The compensated current sensing signal is compared with a constant current reference signal in order to issue a constant current control signal. The device can also be provided to configure the compensating circuit to compensate the constant current reference signal, such that the current sensing signal is compared with the compensated constant current reference signal in order to issue a constant current control signal.
