Application Scenarios & Design Considerations

2.5MHz, 1.5A Synchronous Step Down Regulator

Alternative Part Number

  • TPS62290DRVR --: Pin-compatible 2A step-down converter in 2x2 WSON with similar input range and fixed output options; widely available and drop-in for many SC189LULTRT designs.
  • AP3211KTR-G1 --: 1.5A synchronous buck regulator in SOT-23-6 with comparable switching frequency and efficiency; good low-cost alternative when layout can be adjusted.
  • MP2145GD-Z --: 2A high-efficiency synchronous step-down converter in small QFN package with similar voltage range; strong second-source option for space-constrained designs.
  • MP2143DJ-LF-Z --: 3A synchronous step-down in TSOT-23, higher current margin and similar switching frequency, good drop-in style replacement.
