  • Publication number: 20130088897
    Abstract: An integrated circuit controls a switch of a switching current regulator. The current regulator comprises primary and secondary windings where a first and a second current flow, respectively. The switch is adapted to initiate or interrupt the circulation of the first current in the primary winding. The control integrated circuit comprises a comparator configured to compare a first signal representative of said first current to a second signal and a divider circuit configured to generate said second signal as a ratio of a third signal, proportional to a voltage on the primary winding, with a voltage on a capacitor. The capacitor is charged by a further current controlled by the third signal when the second current is different from zero. The capacitor is discharged through a parallel-connected resistor when the value of said second current is substantially zero.

  • Publication number: 20130057323
    Abstract: An integrated control circuit of a switch is described, which is adapted to open or close a current path; said integrated circuit includes a comparator to compare a first signal with a second signal representative of the current flowing through said current path. The comparator outputs a third variable signal between a low logic level and a high logic level according to whether said second signal is lower than said first signal or vice versa; the integrated circuit has a driver to generate a signal to drive said switch in response to the third signal, and is configured to detect a spike on the leading edge of said second signal and to blank said third signal for a first blanking time period which depends on a turn-on delay of said switch and a second blanking period which depends on the duration of said spike on the leading edge of said second signal.

Memory access is accomplished by one or more memory interfaces, direct coupling of the memory to a bus, or direct coupling of the first device and decoder/encoder to a bus. An arbiter selectively provides access for the first device and/or the decoder/encoder to the memory based on priority. The arbiter may be monolithically integrated into a memory interface. The decoder may be a video decoder configured to comply with the MPEG-2 standard. The memory may store predicted images obtained from a preceding image.
