NCP81140规格书详情
The NCP81140 Multi−Phase buck solution is optimized for
Intel® VR12.5 compatible CPUs with user configurations of 4/3/2/1
phases. The controller combines true differential voltage sensing,
differential inductor DCR current sensing, input voltage
feed−forward, and adaptive voltage positioning to provide accurately
regulated power for both Desktop and Notebook applications. The
control system is based on Dual−Edge pulse−width modulation
(PWM) combined with DCR current sensing providing the fastest
initial response to dynamic load events at reduced system cost. It has
the capability to shed to single phase during light load operation and
can auto frequency scale in light load conditions while maintaining
excellent transient performance.
High performance operational error amplifiers are provided to
simplify compensation of the system. Patented Dynamic Reference
Injection further simplifies loop compensation by eliminating the need
to compromise between closed−loop transient response and Dynamic
VID performance. Patented Total Current Summing provides highly
accurate digital current monitoring.

• True Differential Current Balancing Sense Amplifiers
for Each Phase
• Adaptive Voltage Positioning (AVP)
• Switching Frequency Range of 280 kHz – 600 kHz
• Startup into Pre−Charged Loads While Avoiding False OVP
• Power Saving Phase Shedding
• Vin Feed Forward Ramp Slope
• Over Voltage Protection (OVP) & Under Voltage
Protection (UVP)
• Over Current Protection (OCP)
• VR−RDY Output with Internal Delays
• These are Pb−Free Devices
Applications
• Desktop and Notebook Processors
