POWER MANAGEMENT Description
The SC2647 provides microprocessor core voltage regulation solution up to 4 paralleled PWM channels. The solution can also be configured as 2, 3, or 4-phase form. Multi-phase buck regulator utilizes the phase-shift timing control to allow interleaved switching of the power switches. This architecture minimizes the core voltage ripple and the input current ripple, which leads to optimized voltage regulator design for power density, transient responses, and the thermal performances. To satisfy the highly dynamic nature of the modern microprocessors, the SC2647 adopts peak current mode control topology which ensures wide control loop bandwidth and fast transient responses. The current mode control provides intrinsic phase current matching. The maximum ripple frequency is greater than 1MHz. One of the outstanding features of the SC2647 is its voltage regulation accuracy. Not only it provides better than 0.5% set point accuracy, but also the accuracy to fully complaint with the stringent load line slope specifications mandated by the modern microprocessors. Lossless output current sensing ensures the regulator output voltage is accurately positioned according to the load current condition, and an internal temperature compensation technology further enhances the performance of voltage accuracy. The patented Combi-Sense TM topology is employed by SC2647. The MOSFET Rds(on) and the output inductor winding resistance is used to generate the phase current information. The SC1211VX Combi-SenseTM MOSFET driver plus the SC2647 enables the complete solution. The SC2647 is a multi-platform controller. It conforms to Intel VRM/VRD10.0, VRM9.X, and AMD K-8 (OpteronTM) VID specifications. With very minor changes of the schematic and the layout, the SC2647 based solution can be ported form one platform to another. This greatly benefits the system manufactures for reductions of design cycle and minimize the inventory management.
Multi-Platform Multi-Phase PWM Controller
The VID structure of the SC2647 supports VID-on-Fly applications for any platform. The cycle-by-cycle current limit plus the intelligent over current shut down provide the maximum versatility of the system without false tripping under all possible changes of VID and load conditions. The differential voltage feedback sense eliminates the error caused by high load current on the ground plane. External offset is easy to achieve for any platforms and the VID settings. The enable function is also provided to interface with the corresponding system signal for correct start up timing and shut down timing. (Multiple Patents Pending)
