POWER MANAGEMENT Description
The SC2643VX provides a solution for microprocessor core voltage regulation with up to 4 paralleled PWM channels.
The solution can also be configured as 2, 3, or 4-phase form.
This multi-phase buck
regulator utilizes the phaseshift 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 SC2643VX adopts peak current mode control topology which ensures wide contr...
