Application Scenarios & Design Considerations

Dual Synchronous PWM Controller with Current sharing Circuitry and LDO Controller

Alternative Part Number

  • ISL6520ACBZ --: Single synchronous buck PWM controller in SOIC-8, functionally similar to the IRU3048 controller and widely available; Renesas/Intersil is the direct successor to the IR product line.
  • TPS5430DDA --: Integrated step-down converter with comparable input range and current capability, usable as a drop-in functional replacement in many IRU3048 applications.
  • LM2678S-ADJ --: Simple switcher buck regulator with similar voltage/current ratings, offering an alternative topology solution when the IRU3048 controller is unavailable.
  • TPS40057PWPR --: Wide-input synchronous buck controller with similar voltage-mode control and gate drive capability, suitable for the same DC-DC conversion applications.
  • LTC3851AEGN#PBF --: High-performance synchronous step-down switching regulator controller with comparable features and robust gate drive, usable as an alternative controller in similar designs.
