5019MTC - FAN5019MTC

Description

The FAN5019 is a multi-phase DC-DC controller for implementing high-current, low-voltage, CPU core power regulation circuits.

It is part of a chipset that includes external MOSFET drivers and power MOSFETS.

The FAN5019 drives up to four synchronous-rectified buck channels in parallel.

Features

  • Pin and Function Backward Compatible with FAN53168 and FAN53180 Controllers.
  • Precision Multi-Phase DC-DC Core Voltage Regulation.
  • ±10mV Output Voltage Accuracy Over Temperature.
  • Differential Remote Voltage Sensing.
  • Selectable 2, 3, or 4 Phase Operation.
  • Selectable VRM9 or VRM10 Operation.
  • Up to 1MHz per Phase Operation (4MHz ripple Frequency).
  • Lossless Inductor Current Sensing for Loadline Compensation.
  • External Te.
