The LM2672M-ADJ/NOPB is a monolithic integrated circuit that is a switching regulator with variable output voltage and adjustable output current potentially up to 1.5A. It is suitable for many portable applications such as cellular phones and hand held computers. This switching regulator is housed in a 10-pin MiniSO-10 1.041mm package and is commonly used in the PMIC (Power Management Integrated Circuit) field, including applications such as voltage regulators, DC-DC switching regulators, and other management integrated circuits.

The LM2672M-ADJ/NOPB switching regulator is based on a Pulse Width Modulated (PWM), voltage-mode controller, with an adjustable current limit. It provides an output voltage adjustable from 0.8V up to 5.50V, depending on the input voltage range. The device also features extended temperature range of -40C to 85C and is capable of producing up to 1.5A of output current. The input voltage is adjustable between 4.5V and 28V, and the maximum continuous output power capability is up to 7.5W, making it suitable for low-power portable electronic devices. This regulator\'s frequency can also be adjusted to optimize efficiency, kHz range from 200 kHz to 1 MHz.

The LM2672M-ADJ/NOPB regulator utilizes synchronous rectification techniques to increase efficiency, reduce EMI, and generate less heat. The output voltage accuracy of the device is typically ±2%. The device also offers several protection features such as thermal shutdown, soft-start, cycle-by-cycle limiting, and feedback error protection. The dropout voltage of the device is typically 80-200 mV, making it suitable for low-noise, low-dropout applications such as cellular telephones and hand held electronic devices.

The LM2672M-ADJ/NOPB regulator utilizes internal P-channel MOSFET circuitry and current sensing circuitry, along with external components, to regulate the output voltage. The external current-sense resistor or sense FET is placed between the switcher’s output and ground. As the output current increases, the voltage across this sense resistor increases and the resulting voltage at FB1 is directed to the internal voltage error amplifier. The error amplifier then adjusts the on-time of the switching P-channel FET and maintains a constant output voltage as the load current increases. This technique also helps improve the efficiency of the switch by allowing a much higher switching frequency than would otherwise be possible.

In summary, the LM2672M-ADJ/NOPB is a monolithic integrated switching regulator with several features and advantages. It is capable of providing a constant output voltage, adjustable from 0.8V to 5.50V, and adjustable current limiting from 0mA to 1.5A. Its maximum continuous output power is up to 7.5W, and it operates within an input voltage range of 4.5V to 28V. It also offers several protection features such as thermal shutdown, soft-start, cycle-by-cycle limiting, and feedback error protection. This makes it suitable for portable electronic devices, such as cellular phones and hand held computers.
