Abstract
A switching converter controller includes: a control loop adapted to be coupled to an output terminal of a power stage; and a hybrid hysteretic control (HHC) circuit coupled to the control loop. The HHC circuit includes a resonant capacitor voltage (Vcr) node adapted to be coupled to a resonant capacitor (Cr) of the power stage, where the Vcr node sums a sense voltage for Cr with a frequency compensation ramp. The HHC circuit also includes a soft-start controller coupled to the Vcr node. The soft-start controller includes a clamp circuit coupled to the Vcr node.
