CPU Applications
The NCP5387 is a two−, three−, or four−phase buck controller
which combines differential voltage and current sensing, and
adaptive voltage positioning to power both AMD and Intel
processors. Dual−edge pulse−width modulation (PWM) combined
with inductor current sensing reduces system cost by providing the
fastest initial response to transient load events. Dual−edge
multi−phase modulation reduces total bulk and ceramic output
capacitance required to satisfy transient load−line regulation.
A high performance operational error amplifier is provided, which
allows easy compensation of the system. The proprietary method of
Dynamic Reference Injection (Patented) makes the error amplifier
compensation virtually independent of the system response to VID
changes, eliminating tradeoffs between overshoot and dynamic VID
performance.
Features Meets Intel’s VR 10.0 and 11.0 and AMD Specifications Dual−Edge PWM for Fastest Initial Response to Transient Loading High Performance Operational Error Amplifier Supports both VR11 and Legacy Soft−Start Modes Dynamic Reference Injection (Patented) DAC Range from 0.5 V to 1.6 V �0.5% System Voltage Accuracy from 1.0 V to 1.6 V True Differential Remote Voltage Sensing Amplifier Phase−to−Phase Current Balancing “Lossless” Differential Inductor Current Sensing Differential Current Sense Amplifiers for each Phase Adaptive Voltage Positioning (AVP) Frequency Range: 100 kHz – 1.0 MHz OVP with Resettable, 8 Event Delayed Latch Threshold Sensitive Enable Pin for VTT Sensing Power Good Output with Internal Delays Programmable Soft−Start Time This is a Pb−Free Device*
