The LM20143MHX/NOPB is a synchronous buck regulator designed to deliver up to 3A of continuous output current. It operates within an input voltage range of 2.95V to 5.5V, making it suitable for various low voltage applications. The output voltage is adjustable down to 0.8V, and the switching frequency can be set between 500kHz and 1.5MHz using an external resistor. This device features integrated overvoltage protection (OVP), overcurrent protection (OCP), and a power good signal, enhancing system reliability. It includes a soft-start function to limit inrush currents and can start into pre-biased loads without sinking current. The LM20143MHX/NOPB is packaged in a 16-pin HTSSOP with an exposed thermal pad for improved heat dissipation. It is suitable for applications such as point-of-load regulation for DSPs, FPGAs, and microprocessors, as well as networking and optical communication systems.
