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...
