Abstract
A power conversion apparatus including a flyback power conversion circuit, a control chip and a detection auxiliary circuit is provided. The flyback power conversion circuit receives and converts an input voltage into a DC output voltage. The control chip generates a PWM signal in response to a power supplying requirement to control the operation of the flyback power conversion circuit, wherein the control chip has a single multi-function detection pin. The detection auxiliary circuit assists the control chip to obtain a first detection voltage via the multi-function detection pin, such that the control chip performs a detection of an over temperature protection (OTP) and a detection of an over voltage protection (OVP) synchronously according to the first detection voltage. The first detection voltage is related to the DC output voltage or a thermal voltage of an environment temperature.
