Abstract
A de-glitch switching converting circuit and a controller thereof are provided. In the embodiment of the invention, the circuit can filter noises with high frequency by way of time judgment, so as to avoid the erroneous operation of the controller affecting the stability of the output voltage or the output current. Compared with the method of using low-pass filters with large capacitors to filter noises, highly increasing the cost of the circuit is unnecessary in the embodiment of the invention. The circuit in the embodiment of the invention also has the capability for filtering noises with high amplitudes. In addition, by setting suitable parameters, the circuit in the embodiment of the invention can also avoid affecting the transient response of the circuit while filtering noises.
