<P>PROBLEM TO BE SOLVED: To provide an electrostatic discharge protection circuit capable of removing static electricity of a feedback pin of a voltage conversion chip. <P>SOLUTION: An electrostatic discharge protection circuit of the present invention includes a voltage conversion chip converting an input voltage into an output voltage. The voltage conversion chip includes a feedback pin for receiving a feedback signal and an output pin for outputting the output voltage, and the feedback pin is connected to the output pin. The voltage conversion chip adjusts the output voltage on the basis of the feedback signal to ensure the stability of the output voltage. An electrostatic discharge element is connected between the feedback pin and the ground, and removes static electricity of the feedback pin. <P>COPYRIGHT: (C)2013,JPO&INPIT |
