Abstract: A digital self-start controller, which is functional without fuse and/or trim information. The self-start controller protects a DC-DC converter against large inrush currents and voltage overshoots, while being capable of following a variable VID (voltage identification) reference ramp imposed by the system. The self-start controller uses a relaxation oscillator to set the switching frequency of the DC-DC converter. The oscillator can be initialized using either a clock or current reference to be close to a desired operating frequency. The output of the DC-DC converter is coupled weakly to the oscillator to set the duty cycle for closed loop operation. The controller is naturally biased such that the output supply voltage is always slightly higher than a set point, eliminating the need for any process, voltage, and/or temperature (PVT) imposed trims.

Abstract: A current sensing topology uses an amplifier with capacitively coupled inputs in feedback to sense the input offset of the amplifier, which can be compensated for during measurement. The amplifier with capacitively coupled inputs in feedback is used to: operate the amplifier in a region where the input common-mode specifications are relaxed, so that the feedback loop gain and/or bandwidth is higher; operate the sensor from the converter input voltage by employing high-PSRR (power supply rejection ratio) regulators to create a local, clean supply voltage, causing less disruption to the power grid in the switch area; sample the difference between the input voltage and the controller supply, and recreate that between the drain voltages of the power and replica switches; and compensate for power delivery network related (PDN-related) changes in the input voltage during current sensing.

Abstract: A digital control scheme controls an integrator of a PID filter to implement non-linear control of saturating the duty cycle during which the proportional and derivative terms of the PID filter are set to 0 while the integrator and its internal states (previous values or memory) is set to a duty cycle that is the sum of the current nominal duty cycle plus a deltaD. The deltaD is the maximum duty cycle increment that is used to regulate a voltage regulator from ICCmin to ICCmax and is a configuration register that can be set post silicon. An FSM moves from a non-linear all ON state to an open loop duty cycle which maintains the output voltage slightly higher than the required Vref. After a certain period in this open loop, the FSM then ramps down the open loop duty cycle value until the output voltage is close to the Vref.

Abstract: An apparatus is described which includes a delay-line with reasonably matched delay cells and some logic to ascertain both a correct number of DC-DC converters and interleaving angles or phase offsets. The apparatus measures an operating frequency in real-time in multiples of the individual delay cells of the delay-line. The smaller the period, the higher the load coupled to the DC-DC converters and, therefore the greater the number of DC-DC converters are needed to service the load. The period determines the load and can be used to determine the number of DC-DC converters needed and thereby accomplishing autonomous phase enabling/shedding.
