HOME >>>2006 year news Intersil New Product Information ISL6263 :5-Bit VID Single Phase Graphic Core Voltage Regulator Product Description: The ISL6263 is a precision, single-phase buck GPU/Graphic Core Voltage Controller that uses the Intel Mobile Voltage Positioning (IMVP) to power Graphics Processing Unit (GPU) or Graphics Core. Detailed Description: The ISL6263 is a precision, single-phase buck GPU/Graphic Core Voltage Regulator using the Intel Mobile Voltage Positioning (IMVP) to power Graphics Processing Unit (GPU) or Graphics Core. The heart of the ISL6263 is R3 TechnologyTM, Intersil's Robust Ripple Regulator modulator. Compared with the traditional multiphase buck regulator, the R3 TechnologyTM offers excellent light load efficiency and fast transient response. This is due to the R3 modulator commanding variable switching frequency during a load transient.. Features and customer benefits: Features Benefits Voltage Regulator/Controller 0.5% system accuracy over temperature with enhanced load line accuracy. Internal Gate Driver with 2A Driving Capability Makes a wider selection of MOSFETs available to designers. Microprocessor Voltage Identification Input (MVII) 5-Bit VID Input in variable 0.4120V to 1.2875V in 25.75mV steps. MVII also allows for VID Change on-the-fly. Supports Multiple Current Sensing Schemes Lossless Inductor DCR Current Sensing AND Precision Resistive Current Sensing User Programmable Switching Design flexibility Frequency   Differential Remote CPU Die Voltage Sensing Meets Intel specs Over-voltage, Under-voltage, and Over-current Protection Offers practically fail-safe protection of GPU. Applications: Notebook computers systems LCD (liquid crystal display) PC systems SAN (storage-area network) or NAS (network-attached storage) systems Point-of-Sale (POS) terminals Blade server
