The LM2672M-12 is a DC-to-DC switching regulator, or DC-DC converter, that is used in a range of applications to supply power for electronics. It is an advanced power management integrated circuit (PMIC) specifically designed for powering complex logic, analog, and mixed-signal systems. It is common in mobile phones, laptops, tablets, and various other electronic devices.

The LM2672M-12 is a single-channel regulator that accepts a wide range of input voltages and can generate either 1.2V or 2.5V output voltage. It also has an enable pin that can be used to enable and disable the regulator as needed. The output voltage can be adjusted using an external resistor divider, making it easy to set the output voltage of the regulator.

The device\'s main feature is its switching frequency, which is adjustable from 500kHz to 2MHz. At this frequency, the device can reach peak efficiency of up to 95%, while also providing high power density and low noise. In addition, the device has a low quiescent current of only 12µA, making it ideal for battery operated applications. It also has built-in protection features such as over-temperature and over-current protection.

The LM2672M-12 operates in during three operational modes: pulse-width modulation (PWM) mode, pulse-frequency modulation (PFM) mode, andBurst Mode®. The PWM mode is used to regulate the output voltage with a fast transient response, and is suitable for light loads. The PFM mode works in the same way as the PWM mode, but with lower power dissipation and improved light-load efficiency. Finally, the Burst Mode® mode reduces quiescent current for very light loads, further improving efficiency.

The main applications for the LM2672M-12 include portable computers, digital cameras, cell phones, MP3 players, and other battery-powered devices. This device is ideal for use in space-constrained designs due to its low profile and small size. It is also one of the most popular PMICs in the industry due to its wide range of features and its flexibility.
