LM22672QMRX-ADJ/NOPB is an integrated, high-frequency, and low quiescent current DC/DC switching voltage regulator. It is part of Texas Instruments\' PMIC - Voltage Regulators - DC DC Switching Regulators series, designed to provide high efficiency power conversion and low system cost in a very small package.

The LM22672QMRX-ADJ/NOPB features a wide input voltage range of 1.5 V to 13 V, with an adjustable output voltage ranging from 1.2 V to 10 V. It is capable of delivering up to 3.5 A of continuous output current. The LM22672QMRX-ADJ/NOPB offers excellent transient performance, with fast load-transient response and 1.5% output voltage accuracy over the input voltage range and output current range.

At the heart of the LM22672QMRX-ADJ/NOPB is an internal synchronous rectifier, which eliminates the need for an external Schottky diode and reduces component count, resulting in a more reliable solution with higher efficiencies at light load. It also features a differential remote sense, which is useful in compensating for voltage drops due to the current flow in the output cable.

The LM22672QMRX-ADJ/NOPB contains a comprehensive protection feature set, including cycle-by-cycle current limit, volt-over-temperature protection, overvoltage fault protection, andUndervoltage lockout. It also features a Programmable Soft-Start (PSS), which allows the output voltage of IC to ramp up gradually, reducing sparking at the output and inrush current to the load.

The operating frequency of LM22672QMRX-ADJ/NOPB can be programmed up to a maximum of 2.2 MHz, making it suitable for applications requiring variable switching frequency for the low-noise operation. The LM22672QMRX-ADJ/NOPB is available in a 10-pin TSSOP PowerPAD package and is fully specified over the extended temperature range of -40°C to +125°C. It is suitable for both commercial and industrial applications.

The LM22672QMRX-ADJ/NOPB is an efficient and cost-effective solution for applications such as portable equipment, medical instruments, computers, and appliances requiring a variable input voltage, constant output voltage, and low quiescent current (<2 μA). It is also ideal for high-power loads such as servers, storage systems, and networks.

In summary, the LM22672QMRX-ADJ/NOPB is a high-frequency DC/DC switching voltage regulator from Texas Instruments’ PMIC - Voltage Regulators - DC DC Switching Regulators series, designed to provide high efficiency power conversion and low system cost in a very small package. It offers fast transient response, wide input voltage range, adjustable output voltage, up to 3.5 A of continuous output current, programmable operating frequency, and various protection features.
