An overcurrent detection circuit for a DC-to-DC power converter is disclosed. The overcurrent detection circuit includes a dynamic reference unit for outputting a dynamic reference signal, a load current measurement unit for measuring a load current of the DC-to-DC power converter to output a measurement signal, and a first comparator including a positive input terminal coupled to the load current measurement unit, a negative input terminal coupled to the dynamic reference unit and an output terminal coupled to an overcurrent protection device for outputting an overcurrent protection signal to activate the overcurrent protection device when the measurement signal is greater than the dynamic reference signal. |
