LM2679 Overview

Key Specifications

Mount Type: Surface Mount
Pins: 14
Operating Voltage: 40 V
Min Voltage (typical range): 8 V

Description

The LM2679 series of regulators are monolithic integrated circuits which provide all of the active functions for a step-down (buck) switching regulator capable of driving up to 5A 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

  • Simple and easy to design with (using off-the-shelf external components)
  • Wide input voltage range: 8V to 40V n 260 KHz fixed frequency internal oscillator
  • Softstart capability n -40 to +125˚C operating junction temperature range
