Overview

7-bit, programmable, dual-phase, mobile, CPU, synchronous buck controller.

  • Notebook power supplies for next-generation Intel processors.

  • Single-chip solution fully compatible with the Intel® IMVP-6+ specifications.
  • Integrated MOSFET drivers.
  • Input voltage range of 3.3V to 22V.
  • Selectable 1- or 2-phase operation with up to 1 MHz per phase switching frequency.
  • Guaranteed ±8mV worst-case differentially sensed core voltage error over temperature.
  • Automative power-saving mode maximizes efficiency with light load during deeper sleep operation.
  • Soft transient control reduces inrush current and audio noise.
  • 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 transients.
  • 7-bit, digitally programmable DAC with 0.3V to 1.5V output.
  • Short-circuit protection with latch-off delay.
  • Clock enable output delays the CPU clock until the core voltage is stable.
  • Output load current monitor.
  • 48-lead LFCSP
