Synchronous Buck Controller, 7-Bit, Programmable, Multiphase Mobile CPU

Obsolete

Overview

7-bit programmable multiphase mobile CPU synchronous controller.

  • Notebook power supplies for next generation Intel® processors.

  • 1-, 2-, 3-phase operation at up to 1 MHz per phase.
  • Input voltage range of 3.3V to 22V.
  • ±8 mV worst-case differential sensing error over temperature.
  • Interleaved PWM outputs for driving external high power MOSFET drivers.
  • Automatic power-saving modes maximize efficiency during light load and deeper sleep operation.
  • Active current balancing between output phases.
  • Independent current limit and load line setting inputs for additional design flexibility.
  • 7-bit digitally programmable 0V to 1.5V output.
  • Overload and short-circuit protection with latch-off delay.
  • Built-in clock enable output for delaying CPU clock synchronization until CPU supply voltage stabilizes.
  • Output current monitor.
