摘要： Described is an apparatus having a non-linear control to manage power supply droop at an output of a voltage regulator. The apparatus comprises: a first inductor for coupling to a load; a capacitor, coupled to the first inductor, and for coupling to the load; a first high-side switch couple to the first inductor; a first low-side switch coupled to the first inductor; a bridge controller to control when to turn on and off the first high-side and first low-side switches; and a non-linear control (NLC) unit to monitor output voltage on the load, and to cause the bridge controller to turn on the first high-side switch and turn off the first low-side switch when a voltage droop is detected on the load.

摘要： Described herein is a high-voltage level-shifter (HVLS) that can be used for both NMOS and PMOS bridges, exhibits a higher voltage tolerance for over-clocking than traditional level-shifters, has reduced crowbar current in its input driver, and no contention in its output driver. The HVLS comprises an input driver including a first signal conditioning unit, the input driver operating on a first power supply level and for conditioning an input signal as a first signal in the first signal conditioning unit; and a circuit to receive the first signal and to provide a second signal based at least in part on the first signal, the second signal being level-shifted from the first power supply level to a second power supply level, wherein the second power supply level is higher than the first power supply level.
