2020年9月27日 · LM2596 is a step-down voltage regulator, also known as a buck converter, mainly used to step down the voltage or to drive load under 3A. It carries remarkable load and line regulation and is available in fixed output voltages including 3.3V, 5V, and 12V.

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 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version.

The LM2596 series operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what can be required with lower frequency switching regulators. Available in a standard 5-pin TO-220 package with several different lead bend options, and a 5-pin TO-263 surface mount package.

2017年7月27日 · lm2596是一款常用的降压型直流-直流稳压器，常用于电源设计中，尤其适合需要将高电压转换为较低电压的应用。基于lm2596的电源设计能够提供正负电压输出，这对于很多电子设备，如模拟电路、音频系统或者双电源运算...

Enable Pin: If using the ON/OFF pin, connect it to a logic level signal to enable or disable the regulator. Ensure proper heat dissipation by using a heatsink if necessary, especially when operating at high currents. Keep the input and output capacitors close to the regulator to minimize noise and improve stability.

This pin senses regulated output voltage to complete the feedback loop. The signal is divided by the internal resistor divider network R2, R1 and applied to the non–inverting input of the internal error amplifier. In the Adjustable version of the LM2596 switching regulator this pin is the direct input of the error amplifier and the

Check below circuit diagram for adjustable dc to dc buck converter using LM 2596 ADJ schematic of the IC. The above image is self-explanatory in terms of wiring diagram/ circuit connections. Please ensure that the input voltage must be (1.5 volts) higher than the required output voltage.
