LM70880RRXR is an 80 V, 8 A integrated synchronous buck regulator for high-current industrial and infrastructure power rails.

Best for

  • Wide-input industrial buck rails
  • 48 V to 12 V or 5 V conversion
  • High-current point-of-load power

Avoid if

  • The application requires an output current above 8 A from one phase
  • Board area or thermal design cannot support high-current VQFN power dissipation
  • A confirmed non-exempt RoHS status is mandatory without further compliance review

Check before use

  • Input and switch-node transient voltage
  • External compensation stability
  • Shunt resistor Kelvin sensing
  • Inductor saturation current and thermal rise
