These advanced CPUs and chip sets, combined with this new Intersil Endura(TM) power management solution bring high performance and extended battery life to new transportable notebook PCs running at speeds up to 3.06 GHz. The ISL6247 two- to four-phase controller combined with the ISL6207 MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged driver ICs provide a CPU power solution that offers the industry's highest performance-to-price ratio and supports Enhanced Intel(R) SpeedStep(R) technology, Deep Sleep and Deeper Sleep modes. "Intersil's new Endura ISL6247 PWM controller and ISL6207 MOSFET driver ICs provide an advanced CPU power solution that has already earned wide market acceptance," said Rick Furtney, vice president and general manager of Intersil's High Performance Analog Product Group. "What we offer to our customers with this solution is design flexibility, simplicity, highest accuracy, smallest size, lowest BOM and the industry's highest performance to price ratio. To the mobile PC end-user, this translates into lower cost, higher reliability, longer battery life and optimal performance." The ISL6247 utilizes smart voltage regulation Voltage regulation The change in voltage magnitude that occurs when the load (at a specified power factor) is reduced from the rated or nominal value to zero, with no intentional manual readjustment of any voltage control, expressed in percent of nominal technology to support the Mobile Intel Pentium 4 processor's Active, Deep Sleep, and Deeper Sleep modes. This new PWM IC includes a 6-bit digital-to-analog converter that enables dynamic adjustment of core voltage ranging from 0.8375 V to 1.6 V in 12.5-mV steps. The ISL6247 includes a thermal monitor, which sends a signal to the microprocessor to reduce the load before power system components exceed their maximum thermal limits. ISL6207 MOSFET drivers are used to complete the power solution. These high-voltage MOSFET drivers are optimized to drive both upper and lower N-Channel power MOSFETS at each phase in this synchronous-rectified buck converter topology. The ISL6247 supports loss-less DCR DCR Department of Conservation and Recreation DCR Decrease DCR Digital Cable Ready (television) DCR Dark Crisis (Yu-Gi-Oh! cards) DCR Debt Coverage Ratio DCR Dacryocystorhinostomy , precision resistive resistive /re·sis·tive/ (re-zis´tiv) pertaining to or characterized by resistance. , or low-cost loss-less Rds(on) current sensing methods. It also provides a selectable channel switching frequency ranging from 200 kHz to 1 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. . This provides flexibility in managing the balance between high-speed response, target efficiency, and good thermal management. An integrated thermal sensor adds valuable protection and further reduces the overall power solution cost. Solution voltage accuracy is the industry's best at +/-0.6% guaranteed over temperature. In the near-chip-scale 40-pad 6 X 6 mm Quad Flat No-lead (QFN QFN Quad Flat No-Lead QFN Queen Fan Newsletter (rock band) QFN Quad Flat No Leads ) package, the ISL6247 is the smallest in the industry for this market and application. Its size, thermal efficiency and power efficiency make it ideal for any popular form factor.
