产品详细说明
SIMPLE SWITCHER®电源转换器150千赫
3A降压稳压器
SIMPLE SWITCHER® Power Converter 150 kHz
3A Step-Down Voltage Regulator
需要最少的外部元件数量，这些稳压器使用简单，包括内部频率补偿†和固定频率振荡器。
LM2596系列工作在开关频率为150千赫从而使小尺寸的滤波元件比什么将需要较低频率的开关稳压器。可在一个标准的5引脚TO-220封装，几个不同的铅弯曲选项，以及5引脚TO-263表面贴装封装。
一个标准的系列电感可以从几个不同的厂家优化使用LM2596系列。此功能大大简化了开关模式电源的设计。
其他功能还包括一个保证±4％公差输出电压在指定的输入电压和输出负载条件下，振荡器频率的±15％。外部停机包括在内，具有典型的80μA待机电流。
自我保护功能包括两个阶段的频率减少输出开关和一个完整的保护下过温关断故障电流限制

n个正，负电压转换器The LM2596 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. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation†, and a fixed-frequency oscillator.
The LM2596 series operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Available in a standard 5-lead TO-220 package with several different lead bend options, and a 5-lead TO-263 surface mount package.
A standard series of inductors are available from several different manufacturers optimized for use with the LM2596 series. This feature greatly simplifies the design of switch-mode power supplies.
Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 80 μA standby current.
Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault
conditions.
