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

Application Scenarios & Design Considerations

4 Channel Multiphase Buck DC/DC Controller 24-TSSOP -40 to 85

Alternative Part Number

  • LM5088MH-1 --: Wide-input synchronous buck controller in a different series; similar multi-phase/controller role and available in HTSSOP package, suitable as a functional substitute for power-supply control designs.
  • ISL6566CRZ --: Multi-phase PWM buck controller with comparable voltage-mode control and current sensing features; different naming and vendor, offering a cross-vendor alternative for multiphase regulator designs.
  • ADP3198JCPZ --: Multi-phase synchronous buck controller with similar phase-count and current-sense architecture; a distinct series from another major vendor, usable as a design alternative where layout and compensation are adjusted.
