A non-synchronous boost converter includes a switched Schottky diode to rectify the switched output voltage of the boost converter where the switched Schottky diode has forward conduction blocking capability. The switched Schottky diode has an anode terminal coupled to receive the switched output voltage, a cathode terminal providing the output DC voltage, and a gate terminal coupled to receive a control signal. The control signal has a first state for turning the switched Schottky diode on where the switched Schottky diode conducts current when forward biased and a second state for turning the switched Schottky diode off where forward conduction of the switched Schottky diode is blocked even when the diode is forward biased. The switched Schottky diode can be a JFET controlled or an LDMOS gate controlled Schottky diode. Furthermore, the switched Schottky diode can be formed on-chip or off-chip of the controller circuit of the boost converter.
