LM2674 - SIMPLE SWITCHER Power Converter High Efficiency 500 mA Step-Down Voltage Regulator

This page provides the datasheet information for the LM2674, a member of the LM2 SIMPLE SWITCHER Power Converter High Efficiency 500 mA Step-Down Voltage Regulator family.

Datasheet Summary

Description

The LM2674 series of regulators are monolithic integrated circuits built with a LMDMOS process.

These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 500 mA load current with excellent line and load regulation.

Features

include a guaranteed ± 1.5% tolerance on output voltage within specified input voltages and output load conditions, and ± 10% on the oscillator frequency. External shutdown is included, featuring typically 50 µA stand-by current. The output switch includes current limiting, as well as thermal shutdown for full protection under fault conditions. To simplify the LM2674 buck regulator design procedure, there exists computer design software, LM267X Made Simple. Features n n n n n n n n n n n n n n.
