The LM22672MRE-5.0/NOPB is a volts regulated DC-DC switching regulator designed for use in personal electronics, computer, and telecommunications systems. It is designed to provide a regulated output voltage and current to the load. The switching regulator is based on a two-step process of pulse width modulation (PWO) and overcurrent protection (OCP).PWO is used to regulate the output voltage. The power stage uses a power MOSFET with a voltage feedback loop that monitors the output voltage. When the output voltage falls below the desired set point, the pulse width modulation of the power MOSFET is adjusted to increase the output voltage. When the output voltage exceeds the set point, the pulse width modulation is adjusted to reduce the output voltage. The output voltage is proportional to the width of the PWO pulse.The OCP is used to regulate the output current. The power stage includes an over-current sensing FET, which monitors the load current. When the load current exceeds the threshold set by the OCP, the power MOSFET is turned off and the OCP triggers an output current shutdown.The LM22672MRE-5.0/NOPB is designed to be used in applications such as cellular telephones, notebook computers, and other portable devices. It also has features such as low quiescent current, high efficiency, high power density, and low EMI. The switching regulator supports a wide input voltage range of 3.7V to 18V and an output voltage range of 0.8V to 5V. The LM22672MRE-5.0/NOPB is designed to provide a stable output voltage in the face of varying load current, input voltage and temperature. It also has fast transient response. The switching regulator also provides current-mode control, which ensures that the switching regulator does not oscillate.In addition to the above features, the LM22672MRE-5.0/NOPB includes several protection features. These include thermal shutdown, short-circuit protection, and overvoltage protection. The overvoltage protection feature monitors the input voltage and will shutdown the switching regulator if the input voltage exceeds the maximum rating.Overall, the LM22672MRE-5.0/NOPB is a highly efficient, high power density switching regulator that can provide a regulated output voltage with great precision. Its wide input and output voltage ranges make it suitable for a wide range of applications. Its advanced protection and current-mode control features make it an ideal solution for personal and industrial applications.
