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 is achieved by precision design techniques and trimming of critical elements.
FEATURES
? Allows use of small surface mount components
? Ultra fast transient recovery time

? Selectable internal or external clock
? Soft start, Over current protection
? 5-bit DAC programmable output
? programmable clock, 200Khz-2Mhz per phase
APPLICATIONS
? High end servers and workstations
? High current/Ultra-fast transient microprocessors
? Voltage Regulator Modules
