Overview

The NCP5318 provides full-featured and flexible control conforming to the Intel VRM 10.1 specification for high-performance CPUs. The IC can be programmed as a two-, three- or four-phase buck controller, and the per-phase switching frequency can be as high as 1.0 MHz. Combined with external gate drivers and power components, the controller implements a compact, highly integrated multi-phase buck converter.

  • Programmable 2/3/4 Phase Operation
  • Lossless Current Sensing
  • Enhanced V2 Control Method Provides Fast Transient Response
  • Programmable Up to 1.0 MHz Switching Frequency Per Phase
  • Programmable Adaptive Voltage Positioning
  • Programmable Soft Start Time
  • Differential Current Sense Pins for Each Phase
  • Current Sharing Within 10% Between Phases
  • Programmable Latching Overcurrent Protection
  • Latched Overvoltage Protection
  • Undervoltage Lockout
  • External Enable Control
  • Three-State MOSFET Driver Control through DRVON Signal
  • Pb-Free Package is Available
  • 6-Bit DAC with 0.5% Tolerance Compatible with VRM 10.1 Specification
  • Programmable Lower Power Good Threshold
  • Power Good Output with Delay
  • Pre-set No Load Offset Voltage
