Abstract
A boost converter that provides a wide average current limiting range includes a switch coupled to an inductor output and a power input, a diode coupled to the inductor output and an output terminal load and configured to conduct current in only one direction away from the inductor output and toward the output terminal, a clamp circuit coupled to the diode and the switch, and a minimum time off module coupled to the diode and the switch. The clamp circuit is configured to clamp an inductor output current to a reference current while the converter is operating in a continuous conduction mode (CCM) of operation. The minimum time off module is configured to cause the inductor output current to be zero for at least a time Toff while the converter is operating in a pulse frequency modulation (PFM) mode of operation.
