LM2675M-12/NOPB is a type of DC-DC switch regulator, which belongs to the family of the PMIC (Power Management Integrated Circuit). It is typically used for providing the flexibility to power a wide variety of loads, such as dc-dc power converters, power factor corrected lighting, fan control and motor speed control systems. The device has an integrated step-down voltage regulator with a maximum switching of 2A.

The LM2675M-12/NOPB Implement a current mode control with synchronous rectification and soft-start. The fixed output voltage options range from 1.2V to 26V. This can be extended with an externally adjustable output voltage option, which allows for a range from 0.5V to 26V.

The device will switch off when its input voltage drops below the internal Under-Voltage Lockout Threshold, thus preventing the output from under-voltage. the device can operate in a continuous mode with an external capacitor for output voltage stability. It also provides an internal programmable frequency up to 2.2Mhz Allowing for a small devices footprint.

The LM2675M-12/NOPB integrators a small current sensing circuit and Over Temperature Protection. The device also offers very low power operating mode, limiting the quiescent current to less than 5mA, allowing the entire system to operate with very low power due to its high efficiency power supply.

On the top of the device is a package type called RF (resistor-type), which is 4mm X 4mm in size, and it is considered very small compared to other type of DC-DC converters. The small size is possible due to the integrated power switches, MOSFETs and a dual Schottky diode.

The working principle of LM2675M-12/NOCB is simple yet efficient. Its internal power MOSFET and Schottky diode allow for the regulation of the input voltage and the output current. The current mode regulation ensures fast response and accurate output voltage regulation, improves light load efficiency, reduces output ripple voltage and eliminates any over-voltage conditions at light load.

The LM2675M-12/NOCB has a wide range of applications, it can be used for various applications such as lighting systems, power factor correction, PWM motor control, DCDC converters, battery powered systems, and many other applications. The small size, high efficiency, and simple design make the LM2675M-12/NOCB a good choice for designers. With its wide range of capabilities and features, this device is able to meet the needs of most applications.
