Working Principle

The LM2675LDX-ADJ/NOPB works on the principle of a switch-mode regulator. It utilizes a power MOSFET to temporarily store energy in a small inductor and then discharge it into the output supply. This helps to maintain the output voltage and improve overall efficiency.

The power MOSFET is initially set to a low resistance by the controller, allowing current to flow through the inductor. The stored energy in the inductor is then discharged into the output supply, providing steady, regulated power.

The regulator also features a number of protection features, such as over voltage protection, short circuit protection, and under voltage lock-out. This ensures the system is always functioning correctly and safely.

Conclusion

The LM2675LDX-ADJ/NOPB is a 3A, switch-mode regulated power supply. It is widely used in a variety of industrial and consumer applications, from aerospace and automotive to medical and military. The regulator utilizes a power MOSFET to efficiently regulate the output voltage, while also providing protection features to ensure the system always operates safely.
