DESCRIPTION (CONTINUED)

Other features include an ensured ±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 (Version 6.0).

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
