ADVANCE INFORMATION for pre-production products; subject to change without notice.
Discontinuous Conduction Mode (DCM) operation is employed when the load current is lower than half of the peak-to-peak inductor current. In DCM operation, also known as Diode Emulation Mode, the LS FET is turned off when the inductor current drops below 0 A to keep operation as efficient as possible by reducing switching losses and preventing negative current conduction.
