A process of making inductors for integrated circuit packages may involve forming an inductor upon a magnetic film on a package substrate. Conductors coupled either to a die or a voltage converter extend perpendicularly through the film to conductive plates, defining current paths through and across the film.

Method of manufacturing inductors for integrated circuit packages

A transient voltage compensation system is provided. The transient voltage compensation system includes a processor and a first voltage regulator coupled to the processor, wherein the first voltage regulator is to deliver a load current to the processor at an output voltage. The transient voltage compensation system also includes a second voltage regulator coupled to the first voltage regulator, wherein the second voltage regulator is to regulate the output voltage in response to transient loads of the processor.

Transient voltage compensation system and method

In one embodiment, the present invention includes an apparatus having a substrate with vias extending between first and second surfaces thereof, and at least one helical inductor adapted within a via, which may be formed of a conductive material. Other embodiments are described and claimed.

Inductors for integrated circuit packages

Methods, systems and apparatus for a controller for fast transient response, the controller including a linear compensation circuit for controlling output voltage during steady state operation and a non-linear control circuit to generate a non-linear signal during transient periods, only a first pulse of the non-linear signal is injected during each transient period. The combination linear and non-linear control provides stability and reduces delay times for fast transient response. The non-linear control circuit includes a step up and a step down non-linear control circuit for producing the non-linear signal with a short delay time when the load voltage is less or greater than the reference voltage. An embodiment includes an adaptive circuit or generating a current signal dependent on the load current, the current signal is combined with the output voltage to reduce the difference between the reference and output voltages.

Combination of linear and adaptive non-linear control for fast transient response

A direct current to direct current (DC-to-DC) converter having an active transient voltage compensator (ATVC) coupled with the DC-to-DC converter output terminal to improve a fast transient response of the DC-to-DC converter. The active transient voltage compensator compensates the DC output only during transient operation The ATVC includes a transformer for reducing the ATVC current stresses to improve the compensator efficiency and injecting, absorbing high slew rate current, and a controller circuit for controlling ATVC operation in steady state and normal operation in transients. During step-up load the ATVC operates as a buck converter and during step-down load, the ATVC operates as a boost converter while the main converter operates at low switching frequency for good efficiency.

A pulse width modulation voltage regulator comprises a pulse width modulation circuit and a control circuit. The control circuit is operable to reduce a pulse modulation frequency of the pulse width modulation circuit when a load current increases and to increase the pulse modulation frequency of the pulse width modulation circuit when the load current decreases.

Load-dependent variable frequency voltage regulator

An interposer includes two separate sets of pins, and inserts into two sockets on a printed circuit board. One set of pins supplies power to a step down converter (SDC) mounted on the interposer. The second set of pins provide inputs and outputs to an integrated circuit mounted on the interposer. One or more conductive traces in or on the interposer electrically connect an output of the SDC to an input of the integrated circuit, thus supplying regulated power to the integrated circuit through the interposer. The SDC and integrated circuit can be directly mounted on the interposer, or either or both can be mounted on packages that connect to the interposer. The SDC and integrated circuit can be flip chips or can be connected to the interposer or package using wirebonds. The packages can be pinned or connectable by solder bumps.
