The LM2672N-3.3/NOPB is a single high efficiency, synchronous step-down DC-DC converter with a 3.3V output voltage. This type of device is often used in cost- and space-sensitive applications, such as hand-held electronics, and other portable devices. The LM2672N-3.3/NOPB is part of a family of DC-DC regulators from Texas Instruments, and is classified as a PMIC (Power Management Integrated Circuit). It belongs to the Voltage Regulators group, and more specifically to the DC DC Switching Regulators family.

It is a monolithic Regulating Pulse Width Modulator (PWM) and provides excellent line and load regulation. The integrated circuit features a wide input operating voltage range of 3.2V to 18V, and provides up to a maximum output current of 1.5A. It is optimized for low input voltage, low voltage output (Step-Down configurations) and supports 1.2MHz operation. The product is tested and included in the Texas Instruments\' WEBENCH Power Architect Tool design environment.

The LM2672N-3.3/NOPB is based on a Pulse Width Modulation (PWM) topology and utilizes synchronous rectification to achieve efficiencies of up to 95%. It is equipped with internal soft-start and adjustable output voltage, plus the ability to synchronize with an external clock. The entire device can be configured in a wide variety of modes, however, for optimal performance, it is recommended to use the PowerSaveTM mode.

The product also includes over-voltage protection, under-voltage protection, and over-temperature protection in order to protect both the device, and the load. Additionally, the device has thermal shutdown protection, over-current protection, output current limit and cycle-by-cycle current limit protection, plus short-circuit protection.

The LM2672N-3.3/NOPB is packaged in a 6 pin, 3mm x 3mm PowerPAD VFQFN package and is designed to work at a temperature range of -40oC to 125oC.

In summary, the LM2672N-3.3/NOPB is a high efficiency, single DC-DC synchronous step-down converter from Texas Instruments that provides up to 1.5A of current with a 3.3V output voltage. It is part of the Texas Instruments family of DC-DC regulators and is classified as a PMIC (Power Management Integrated Circuit), part of the Voltage Regulators group, and more specifically the DC DC Switching Regulators family. This product includes over-voltage protection, under-voltage protection, and over-temperature protection, as well as thermal shutdown protection, over-current protection, output current limit and cycle-by-cycle current limit protection, plus short-circuit protection.
