The LM2672MX-ADJ is a current-mode switch-mode DC-DC buck regulator chip manufactured by Texas Instruments. It is designed to accommodate a wide range of input voltage and current requirements and takes precision output voltage and current measurements accurately. The LM2672MX-ADJ is a step-up DC-DC converter designed for use in industrial, automotive, and other applications requiring a low output voltage, high efficiency, and fast load transient response.

The LM2672MX-ADJ can be used to reduce the input voltage to a desired level and/or maintain the output voltage at a constant level when exposed to a wide variety of load conditions. For example, the LM2672MX-ADJ can be used to regulate the input voltage to a minimum level of 3.1V and a maximum level of 37V. The chip also offers overcurrent, overtemperature and output voltage protection features.

The LM2672MX-ADJ is controlled using a 1.6V ±10% internal reference (VREF) and features an adjustable current limit. The voltage error amplifier and an external feedback resistor setup the output voltage. The output voltage is adjusted with an external sense resistor. The chip operates in the constant-frequency, current-mode PWM (pulse-width modulation) buck mode. A maximum duty cycle of 99.9% is achieved by reducing the PWM frequency.

The LM2672MX-ADJ has a wide range of applications in industrial and automotive systems such as control and instrumentation, audio and video, lighting, relay drivers, and servo control. The LM2672MX-ADJ can be used to power low-voltage DC motors, LEDs, and pulse-width modulation (PWM) loop controllers.

In summary, the LM2672MX-ADJ is a step-up DC-DC converter designed for use in industrial, automotive, and other applications requiring a low output voltage, high efficiency, and fast load transient response. It is controlled using a 1.6V ±10% internal reference (VREF) and features an adjustable current limit. The voltage error amplifier and an external feedback resistor setup the output voltage. The output voltage is adjusted with an external sense resistor and the chip operates in the constant-frequency, current-mode PWM (pulse-width modulation) buck mode. The LM2672MX-ADJ is ideal for applications requiring precise output voltage and current measurements. The chip is also suitable for use in low-voltage DC motor, LED and PWM loop controllers, and other industrial and automotive systems.
