Key Features

  • Wide 4.5V to 42V input voltage range supports diverse industrial and automotive power rail designs
  • Constant on-time control with 0.9V reference enables fast transient response and tight output regulation
  • Dual-mode operation: fixed 0.9V output or adjustable output from 1.9V for flexible power design
  • Non-synchronous PFET buck topology simplifies gate drive circuitry and reduces component count
  • Compact 8-MSOP-PowerPAD package with -40°C to 125°C range suits harsh environment applications

Applications

The LM25085AMY/NOPB is well suited for industrial power supplies, automotive electronics, and distributed power systems requiring a wide input range. Its constant on-time PFET buck topology makes it ideal for point-of-load converters in telecom infrastructure, factory automation equipment, and embedded computing platforms. The adjustable output mode and wide temperature rating also support demanding applications in test and measurement instruments and motor drive control systems.
