Abstract: A power converting device includes a power transistor, a detecting device, a signal converter and a controller. The detecting device obtains a detection voltage by detecting an output voltage on the output end of the power converting device and a detection current by detecting an operation current of the power transistor. The signal converter converts the detection voltage from a first format to a second format, and converts the detection current from the first format to the second format. The controller receives the detection voltage and the detection current in the second format. Wherein the controller compares the detection voltage with a first voltage threshold value and a second voltage threshold value to adjust a control code, and generates a control signal to a control end of the power transistor according to the control code.
