The IR3721 is a versatile power or current monitor IC for low-voltage DC-DC converters.
The IR3721 monitors the inductor current in buck or multiphase converters using either a current sensing resistor or the inductor’s winding resistance (DCR).
The output (DI) is a pulse code modulated signal whose duty ratio is proportional to the inductor current.
