Abstract
In examples, an apparatus includes a transistor, a switch, a diode, a capacitor, a voltage divider, a second transistor, a resistor, and a controller. The transistor has a transistor drain, a transistor source, and a transistor gate. The switch is adapted to couple a power supply to the transistor drain through an inductor. The diode has a cathode and an anode, the diode cathode coupled to the transistor drain. The capacitor is coupled between the diode anode and ground. The voltage divider is coupled between the diode anode and ground and having a voltage divider output. The second transistor has a second transistor source and a second transistor gate. The resistor is coupled between the diode anode and the second transistor source. The controller is coupled to the transistor gate, the transistor source, the voltage divider output, the diode anode, the second transistor gate, and the second transistor source.
