com POWER MANAGEMENT Description The SC2642 provides microprocessor core voltage regulation solution with two paralleled PWM channels.
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 SC2642 adopts peak current mode control topology which ensures wide control loop bandwidth and fast transient responses.
The current mode control provide...
