DESCRIPTION
The SC1144 is a high performance, multi-phase (PWM) controller designed for high power microprocessors requiring ultra fast transient response, such as ® the Pentium ll and beyond.
Utilizing a novel and unique design, the controller distributes the output load across (up to) four converter channels by digitally phase shifting the PWM outputs.
This approach greatly reduces the stress and heat on the output stage components while lowering input ripple current by as much as 80%.
Accurate current sharing among the four phases ...
