IR3538A - Digital Multi-Phase Buck Controller

Download the IR3538A datasheet PDF. This datasheet also covers the IR3536A variant, as both devices belong to the same digital multi-phase buck controller family and are provided as variant models within a single manufacturer datasheet.

Description

The IR3536A and IR3538A are dual-loop digital multi-phase buck controllers.

The IR3536A drive up to 6 phases and the IR3538A drives up to 8 phases.

The IR3536A and IR3538A are fully Intel® VR12 and AMD® SVI/PVI compliant on both loops and provide a Vtt tracking function for DDR memory.

Features

  • 6-phase & 8-phase dual output PWM Controller.
  • Phases are flexibly assigned between Loops 1 & 2.
  • Intel® VR12, AMD® 3.4MHz SVI/PVI & Memory modes.
  • Overclocking & Gaming Mode with Vmax setting.
  • Switching frequency from 200kHz to 1.2MHz per phase.
  • IR Efficiency Shaping Features including Variable Gate Drive and Dynamic Phase Control.
  • Programmable 1-phase or 2-phase for Light Loads and Active Diode Emulation for Very Light Loads.
  • IR Adaptive Transient Algorith.
