Working Principle

The LM2700MTX-ADJ/NOPB DC-to-DC switching regulator works on a buck switching topology. The input voltage is switched on and off to control the voltage of the output. The regulator contains an internal MOSFET for power conversion and an internal low-dropout regulator for accurate output voltage control. The switching frequency can be adjusted with an external resistor. The device also has a built-in soft start and synchronous rectification for improved efficiency.

The regulator can operate with an input supply voltage up to 28V. The integrated protection features protect the output from short circuit, over-current, and over-voltage. The ability to monitor the output voltage and current make it suitable for complex systems in which precision and control are required.

The LM2700MTX-ADJ/NOPB is capable of delivering up to 3A of continuous output current and 12A of peak output current at 0.5V of dropout voltage. The adjustable output voltage range is 0.6V to 5.5V. It is available in a small TSOT-23-5 package for space-constraint applications.

Conclusion

The LM2700MTX-ADJ/NOPB is a low power, high efficiency DC-to-DC switching regulator with adjustable output voltage. Its robust construction with protection features makes it well suited for demanding applications, from consumer electronics to automotive and medical devices. Its adjustable switching frequency and built-in synchronous rectification for improved efficiency are additional benefits for this versatile device.
