                         3A降壓轉換調節器--AT2596

            一 概述

            The AT2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator capable of driving a 3A load with excellent line and load regulation.
            Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation,and a fixed-frequency oscillator. A standard series of inductors are available from several different manufacturers optimized for use with the AT2596 series. This feature greatly simplifies the design of switch-mode power supplies. The output voltage is guaranteed to ±3% tolerance under specified input voltage and output load conditions. The oscillator frequency is guaranteed to ±15%. External shutdown is included, featuring typically 100µA standby current. Self protection features include a two stage frequency current limit for the output switch and an temperature shutdown for complete under fault conditions.
