General Description

The LM22679 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 5A loads with excellent line and load regulation characteristics.

High efficiency (>90%) is obtained through the use of a low ON-resistance N-channel MOSFET.

The series consists of a fixed 5V output and an adjustable version.

Overview

LM22679 5A SIMPLE SWITCHER®, Step-Down Voltage Regulator with Adjustable Soft-Start and Current Limit October 17, 2008 LM22679 5A SIMPLE SWITCHER®, Step-Down Voltage Regulator www.datasheet4u.

Key Features

such as external component calculation, electrical simulation, thermal simulation, and Build-It boards for easy design-in. The switching clock frequency is provided by an internal fixed frequency oscillator which operates at 500 kHz. The LM22679 series also has built in thermal shutdown and current limiting. The current limit threshold can be adjusted using an external resistor. An adjustable soft-start feature is provided by selecting an appropriate external soft-start capacitor. Features.
