1. A system, comprising:
a differential amplifier having a first input terminal and a second input terminal, the differential amplifier configured to be coupled to a boost diode of a boost converter;
an input diode coupled to the first input terminal and the second input terminal;
a pull-up circuit coupled to the input diode and configured to be coupled to the boost diode;
a pull-down circuit coupled to the pull-up circuit; and
a transistor coupled to the pull-up circuit and the pull-down circuit.
