Configuring the operational behavior of an integrated circuit. The integrated circuit (IC) comprises a plurality of configuration inputs for configuring the IC. The IC also has a memory which stores a plurality of sets of parameter values. Each parameter value of the respective set corresponds to a different operational parameter of a plurality of operational parameters. The IC includes logic which determines a first plurality of configuration values corresponding to the first plurality of configuration inputs. The logic then selects a set of parameter values from the stored plurality of sets of parameter values. The selection of parameter values is based on the first plurality of configuration values. The IC is then configured for operation according to one or more operational parameter values in the selected set of parameter values.

Application specific power controller configuration technique

Complex filters may be used to achieve compensation of a plant, corresponding for example to a power regulator or point-of-load (POL) regulator. Digital filter coefficients may be mapped to analogous poles and zeros, or they may be mapped to values of the quality factor (Q) of the output, frequency, and gain. The plant may be observed and characterized using a network analyzer to generate the Bode plot (or Nyquist plot) for the plant. The digital filter coefficients may be mapped to features that may be identified on the Bode plot (or Nyquist plot) to easily correlate characteristics of the digital filter or digital compensator to the plant characteristics. The mapped features may be adjusted, for example by a user, either manually or by executing one or more optimization algorithms, to achieve the desired results relative to the Bode plot (or Nyquist plot). The mapped features may then be reverse mapped to the digital filter or digital compensator coefficients to fine tune and implement the digital filter or digital compensator.

Adaptive compensation in digital power controllers

Sensing current flowing through a semiconductor device includes providing an input pin to receive an input, providing an output pin coupled to a predefined voltage source, providing a control pin to receive a control signal for controlling a flow of current between the output pin and the input pin, and electrically coupling a Kelvin sense pin to an output pad located on a semiconductor die of the device. An electrical path from the output pad to the output pin has a predefined resistance. The current is Kelvin current sensed using the predefined resistance. A flow of an output current provided to a load coupled to the device is interrupted when a value of the current is greater than a predefined value.

Method of Kelvin current sense in a semiconductor package

Regulating a direct current-to-direct current (DC-DC) converter, a semiconductor switch having an improved current sensing technique is used to switch a DC voltage input at a predefined frequency. The switch includes a control pin to receive a control signal for controlling a current flowing between an input pin and an output pin. The switch also includes a Kelvin sense pin electrically coupled to an output pad located on a semiconductor die of the device for sensing the current. An electrical path from the output pad to the output pin in the form of a conductive lead wire has a predefined resistance. The current is Kelvin current sensed using the predefined resistance to tightly control deviation in the current beyond a predefined range.

Power down to a reduced power state, such as a standby or off state, of an information handling system is delayed by a user-configured time after detection of closing of the cover of the information handling system. In one embodiment, a cover delay module associated with the BIOS of the information handling system delays communication of the detection of the closing of the cover from the BIOS to a power manager of the operating system that commands the reduced power state. In another embodiment, the cover delay module integrates with the operating system power manager.
