L6983 - 38V 3A synchronous step-down converter

Description

The L6983 is an easy to use synchronous monolithic step-down regulator capable of delivering up to 3 A DC to the load.

The wide input voltage range makes the device suitable for a broad range of applications.

Features

  • 3.5 V to 38 V operating input voltage.
  • Output voltage from 0.85 V to VIN.
  • 3.3 V and 5 V fixed output voltage versions.
  • 3 A DC output current.
  • 17 μA operating quiescent current.
  • Internal compensation network.
  • Two different versions: LCM for high efficiency at light loads and LNM for noise sensitive.
