Abstract
The present disclosure provides a voltage conversion circuit and a voltage conversion chip. A problem that an overcurrent protection signal is falsely triggered can be solved by connecting a first diode in series between an output terminal and an input terminal of a voltage conversion module. The present disclosure provides the voltage conversion chip. A negative voltage capability of an output pin of the voltage conversion chip is increased by setting a comparator and a constant voltage source.
