Overview

7-Bit, Programmable, 3-Phase, Mobile CPU Synchronous Buck Controller

  • Notebook power supplies for next-generation Intel® processors
  • Single-Chip Solution
  • Fully compatible with the Intel® IMVP-6.5 specifications
  • Selectable 1-, 2-, or 3-phase operation with up to 1 MHz per phase switching frequency
  • Phase 1 and phase 2 integrated MOSFET drivers
  • Input voltage range of 3.3V to 22V
  • Guaranteed ±8 mV worst-case differentially sensed core voltage error over temperature
  • Automatic power-saving mode maximizes efficiency with light load during deeper sleep operation
  • Active current balancing between output phases
  • Independent current limit and load line setting inputs for additional design flexibility
  • Built-in power-good blanking supports voltage identification (VID) on-the-fly (OTF) transients
  • 7-bit, digitally programmable DAC with 0.3V to 1.5V output
  • Short-circuit protection with programmable latchoff delay
  • Clock enable output delays the CPU clock until the core voltage is stable
  • Output power or current monitor options
  • 48-lead QFN 7x7mm (ADP3212A), 48-lead QFN 6x6mm (NCP3218A)
  • These are Pb-free devices
  • Fully RoHS compliant
