ABSTRACT:
A DC-DC high frequency boost converter with a supply voltage input (110), a boosted voltage output (112), a series circuit of an inductor (114) and a rectifying device (116) connected in series between said supply voltage input (110) and said boosted voltage output (112), has a switch (124) connected between ground and a connection node (120) of said inductor (114) and said rectifying device (116). A control circuit (126) is provided for controlling said switch (124), and a zero inductor current detection circuit (128) is provided that compares a voltage (Un) on said connection node (120) with a reference voltage (Uref) and provides a zero inductor current indication (Comp) when both voltages are equal.
