• Typical Application for SC2643 2, 3 or 4 Phase Combi-Sense PWM Controller. The SC2643 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. Multiphase 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 thermal performances
