Circuit compensating controller

The invention provides a circuit compensating controller. The circuit compensating controller comprises a compensation circuit, a resistor, a current sampling load and a high level diode, wherein one end of the resistor is connected with a high voltage end of an input voltage; the other end of the resistor is connected in series with one end of the current sampling load, and the other end of the current sampling load is connected with a low-voltage end of the input voltage; and a cathode of the high level diode is connected with the compensation circuit, and an anode of the high level diode is connected between the resistor and the current sampling load. The circuit compensating controller provided by the invention can protect the compensation circuit from being burned.
