摘要： An electrical fuse and a process of programming the same are presented. An electrical fuse comprises a lower level silicide layer on a non-doped or lightly-doped polysilicon layer, an upper level conductive layer, and a tungsten contact coupled between the lower level silicide layer and the upper level conductive layer. The tungsten contact and a neck portion of the silicide layer are the programmable portion of the electrical fuse. High post-programming resistance is achieved by a first programming phase that depletes silicide in the silicide layer, followed by a second programming phase that depletes tungsten in the tungsten contact.

摘要： A multi-phase power converter with constant on-time control includes a plurality of channels to convert an input voltage into an output voltage, and each of the channels is driven by a control signal. When all channel currents of the channels are balanced, each of the control signals remains a constant on-time. When the channel currents are imbalanced, the on-times of the control signals are modulated according to the difference between each channel current and a target value for current balance between the channels.

摘要： A DCR sense scheme is provided to sense the inductor current of a COT power converter. The DCR sense is implemented by using the direct current resistance of the output inductor of the COT power converter, and thus eliminates the ESR limitations on the type of output capacitors for stability concern. A quick response mechanism is further incorporated in the COT power converter to speed up the transient response of the COT power converter.
