NCP5385
2/3/4 Phase Buck Controller
for VR10 and VR11 Pentium
IV Processor Applications
The NCP5385 is a two ? , three ? , or four ? phase buck controller
which combines differential voltage and current sensing, and
adaptive voltage positioning to power Intel’s most demanding
Pentium ? IV Processors and low voltage, high current power
supplies. Dual ? edge pulse ? width modulation (PWM) combined with
inductor current sensing reduces system cost by providing the fastest
initial response to transient loads thereby requiring less bulk and
ceramic output capacitors to satisfy transient load ? line requirements.
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 the need for tradeoffs between load transients
and Dynamic VID performance.
Features
? Meets Intel’s VR 10.0, 10.1, 10.2, and 11.0 Specifications
? Dual ? Edge PWM for Fastest Initial Response to Transient Loading
? High Performance Operational Error Amplifier
? Supports both VR11 and Legacy VR10 Soft ? Start Modes
? Dynamic Reference Injection (Patented)
? 8 ? Bit DAC per Intel’s VR11 Specifications
? DAC Range from 0.5 V to 1.6 V
? " 0.5% System Voltage Accuracy
? 2, 3, or 4 ? Phase Operation
? 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)
? Fixed No ? Load Voltage Positioning at –19 mV
? Frequency Range: 100 kHz–1.0 MHz
? Threshold Sensitive Enable Pin for VTT Sensing
? Power Good Output with Internal Delays
? Programmable Soft ? Start Time
? Operates from 12 V
? This is a Pb ? Free Device*
Applications
? Pentium IV Processors
? VRM Modules
