Latest Patents

Qian Li holds a patent titled "Synchronizing hiccup over-current protection of multiphase switching converters." This invention involves a multiphase switching converter that includes a first switching converter circuit with a power stage connected to a DC voltage supply and a controller. The controller features an over-current (OC) circuit that detects OC events and sets a command signal to a preset low value upon detection. It also provides a first hiccup signal. A synchronization circuit generates a second hiccup signal based on the command signal of the OC circuit and a sampled portion of the output voltage of the power stage. A hiccup timer is triggered by either the first or second hiccup signal to initiate a hiccup pulse.
