LM2676 Overview

Key Specifications

Package: TO-220
Mount Type: Through Hole
Pins: 7
Operating Voltage: 40 V

Description

The LM2676 series of regulators are monolithic integrated circuits which provide all of the active functions for a stepdown (buck) switching regulator capable of driving up to 3A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low ON-resistance DMOS power switch.

Key Features

  • Efficiency up to 94%
  • Simple and easy to design with (using off-the-shelf external components)
  • 150 mΩ DMOS output switch
  • 3.3V, 5V and 12V fixed output and adjustable (1.2V to 37V ) versions
  • 50μA standby current when switched OFF
