Introduction

LM2650MX-ADJ/NOPB is a switching regulator manufactured by Texas Instruments, used for controlling the DC output voltage of electronic circuits. It consists of an On-board synchronous Buck controller and MOSFETs, which allow the user to adjust the output voltage settings. This device is designed to operate in high power applications such as lighting circuits and industrial power supplies.

Application Field

LM2650MX-ADJ/NOPB is suitable for use in various kinds of applications, such as high power LED lighting, induction heating, variable power supplies, AC-DC conversion, and general purpose voltage regulation. It can be used for a wide range of input voltages – ranging from 6V to 80V. This flexibility offers a wide range of possibilities for industrial and commercial applications that require high power and reliable voltage regulation.

Working Principle

The heart of LM2650MX-ADJ/NOPB is the patented, synchronized, constant on-time (COT) peak current mode control, which allows the device to regulate the output voltage in a smooth and efficient way. The COT control is based on a simple, closed-loop, peak current-mode control. In this mode, the output voltage is regulated by modulating the voltage drop across an output inductor. The device constantly monitors the output voltage and adjusts the COT accordingly. This makes the device highly efficient, especially when it is operated at low output voltages. The on-board MOSFETs provide the necessary switching, which is accounted for by their efficient power distribution. The synchronous design ensures that both MOSFETs are switched in a complementary manner, so that there is no power loss. The current mode control eliminates the need for external compensation components, making the device cost effective and easy to use.

Conclusion

In conclusion, the LM2650MX-ADJ/NOPB is an efficient, cost effective, and easy to use switching regulator. Its COT control and synchronous design allow it to operate in a wide range of input voltages and at high power levels. This makes it suitable for a wide range of applications, such as LED lighting, induction heating, variable power supplies, and AC-DC conversion.
