The LM2661MM/NOPB is a DC to DC switching regulator produced by Texas Instruments. This device is used in a variety of applications including industrial and consumer electronics, battery management systems, and communications systems. It is a cost-effective solution for power supply design constraints such as high output current, fast transient response, and a tight voltage accuracy.

The LM2661MM/NOPB is a synchronous buck regulator which has two terminals, an output and a control terminal. The output terminal is the source of power for the load and the control terminal is used for feedback, enabling the LM2661MM/NOPB to accurately regulate the output voltage.

The LM2661MM/NOPB has a wide input voltage range with a maximum input voltage of 36V. This allows the LM2661MM/NOPB to operate with a wide variety of input sources, and the voltage range can be finely adjusted with the use of external resistor dividers. The output voltage can be set from 0.8V to 5.25V with an accuracy of ±2% and a ripple rejection of 80dB, ensuring a stabile voltage delivery to the load.

The LM2661MM/NOPB also has a fast transient response which provides a higher than normal load transient protection. This fast response protects the load from voltage or current surges, significantly improving the system reliability. Furthermore, the LM2661MM/NOPB is highly efficient, with a maximum efficiency of 89%. This helps to reduce the power dissipation of the system, reducing the overall power losses.

The LM2661MM/NOPB can operate in either discontinuous or continuous mode depending on the required application and power requirements. In discontinuous mode, the device operates at a lower frequency enabling it to have higher efficiency, whereas in continuous mode the device operates at a higher frequency, providing better current regulation and transient response.

In addition to the above features, the LM2661MM/NOPB is also equipped with a built-in power good indicator, which can be used to monitor the status of the system power supply. It also has a built-in current limit circuit which can be configured to operate in either short circuit protection mode or in current limiting mode. This protection feature helps to prevent damage to the system in case of an over current event.

The LM2661MM/NOPB is a cost-effective solution for DC to DC switching regulators, supporting a wide range of inputs and outputs while having high efficiency, fast transient response, and robust protection features.
