This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage Positioning

Alternative Part Number

  • ADP3198JCPZ-RL --: Multiphase buck PWM controller with similar VRM control function and VID interface, suitable as a functional replacement in CPU power designs.
  • NCP5386MNR2G --: Multiphase synchronous buck controller offering comparable PWM regulation features and a different naming series, making it a clear alternative.
  • TPS40090PWR --: Multiphase buck controller with similar voltage-mode control and current sensing, usable as a cross-reference alternative from a different vendor family.
  • HIP6311ACBZ --: Multi-phase PWM buck controller from the same Intersil/Renesas family with similar voltage-mode control and driver interface, often used as a drop-in for ISL6558 designs.
  • NCP5386BMNR2G --: Two-phase synchronous buck controller with comparable PWM output and current-sense features, suitable as a functional replacement in CPU/core VRM applications.
