MAX8809A Overview

Description

The MAX8809A/MAX8810A synchronous, 2-/3-/4phase, step-down, current-mode controllers with integrated dual-phase MOSFET drivers provide flexible solutions that fully comply with IntelĀ® VRD11/VRD10 and AMD K8 Rev F CPU core supplies. The flexible design supplies load currents up to 150A for low-voltage CPU core power requirements.

Key Features

  • prevents negative voltage spikes on the output at turn-off, eliminating the need for an external Schottky clamp diode
  • Either the inductor DCR or a resistive current-sensing element is used for current sensing
  • When used with DCR sensing, rapid active current averaging (RA2) eliminates the tolerance effects of the
