The LM2673SD-12/NOPB is a member of the LM2673 voltage regulator series, which is a set of switching voltage regulators featuring step-down voltage converters. The LM2673 was designed by National Semiconductor and is used in many consumer and industrial electronics these days. It is a highly- featured and high-performance device that has a wide regulating range and low tolerance voltage regulation.The LM2673SD-12/NOPB has a wide input voltage range of 4.5V to 18V. It provides up to 0.95A of current with a very low operating temperature range of -40°C to 125°C. The LM2673SD-12/NOPB is a highly efficient device that can provide up to 95% efficiency at full load. It also has a very low dropout voltage (Vdo) of 0.4V, which means that it can deliver a stable output even when the input voltage drops.The LM2673SD-12/NOPB application field is mainly focused on battery-operated systems, computers, and other types of electronic equipment. It is also suitable for automotive and various other high-energy applications. The LM2673SD-12/NOPB can be used to regulate a variety of voltages including, 1.5V, 1.8V, 2.5V, and 3.3V.The LM2673SD-12/NOPB works on the principle of Pulse Width Modulation (PWM). The internal synchronous rectifier of the device allows the generator of the PWM signals to accurately control the output voltage by varying the duty cycle. PWM can be thought of as a type of on-off switch that opens and closes at a fixed frequency. By controlling the duty cycle, the output voltage can be adjusted over a wide range and with a very high accuracy. Furthermore, the device is equipped with an internal voltage reference that allows for accurate voltage regulation over a temperature range of -40°C to +125°C, even at light load and in the presence of transients.The LM2673SD-12/NOPB also has a number of other features such as it can be enabled/disabled through an external pin, it has internal soft-start function and current limit protection. All of these features make the device very versatile and suitable for a wide range of applications.In conclusion, the LM2673SD-12/NOPB switching regulator can be used for a number of different applications such as battery-operated systems, automotive systems, computers, and other types of electronic equipment. It has an impressive range of features and its low dropout voltage and efficiency make it a suitable choice for energy-intensive applications. The device’s wide regulating range and low tolerance voltage regulation makes it a great choice for voltage regulators.
