The LM2596 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step-down switching regulator (buck converter). All circuits of this series are capable of driving a 3.0A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5.0V,12V, and an adjustable output version. These regulators were designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2596 are offered by several different inductor manufacturers. Since the LM2596 converter is a switch- mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages. In many cases, the power dissipated is so low that no heatsink is required or its size could be reduced dramatically. A standard series of inductors optimized for use with the LM2596 are available from several different manufacturers. This feature greatly simplifies the design of switch- mode power supplies. The LM2596 features include a guaranteed +/- 4% tolerance on output voltage within specified input voltages and output load conditions, and +/-15% on the oscillator frequency (+/- 2% over 0°C to 125°C). External shutdown is included, featuring 80μA (typical) standby current. Self-protection features include a two stage frequency reducing current limit for output switch and an over temperature shutdown for complete protection under fault conditions.

產品說明
LM2596 系列為單晶片整合式電源調節器，非常適合用於簡單且方便的降壓型開關穩壓器（Buck Converter）設計。此系列所有裝置均具備驅動 3.0A 負載的能力，並在輸入電壓與負載變動下仍可維持優異的線性與負載調節性能。
本系列提供固定輸出電壓版本（3.3V、5.0V、12V）及可調式輸出版本。這些穩壓器經過最佳化設計，能夠最小化所需的外部元件數量，從而簡化電源供應設計流程。
目前已有多家電感製造商提供專為 LM2596 最佳化設計的標準電感系列，使設計開關式電源變得更加便利。由於 LM2596 為開關模式電源，其效率遠高於傳統三端子線性穩壓器，尤其是在輸入電壓較高的情況下差異更為顯著。在多數應用中，其功耗極低，甚至不需使用散熱片，或可將散熱片尺寸大幅縮小。
