IR3087MTR is a high performance single phase synchronous buck regulator controller with integrated MOSFETs. It offers integrated system level protection features and operates with supply voltages between 9V and 60V. It is capable of delivering up to 6A of continuous output current, allowing system designs to minimize external components and minimize design cost. It is widely used for providing power for FPGAs, DSPs, ASICs, MCUs and other digital circuits in industrial and consumer products.

IR3087MTR is designed with a world-class synchronous PWM control system, providing excellent dynamic and static performance, low input current and high utilization efficiency. The controller has an internal compensation network, eliminating the need for an external compensation. It also supports external synchronization to avoid interference from the incoming power frequency and neighboring clocks. Additionally, it features adaptive voltage scaling, burst-mode operation, adjustable output voltage and overload protection, as well as over-temperature protection.

The IR3087MTR synchronous buck regulator controller has a lot of advantages over other types of power management solutions, such as linear regulators and other buck controllers. Firstly, it is more efficient than the other solutions, since it reduces the power lost in the conversion process, resulting in higher system utilization and better efficiency. Secondly, it is more reliable because it reduces the effects of transients and ripple in the input power. Thirdly, it is cost-effective because it requires fewer external components and maintains smaller form factors compared to other solutions. Finally, it is a high performance solution, providing excellent current and voltage regulation, as well as high utilization efficiency.

IR3087MTR is an ideal solution for applications where fast transition times are needed, such as servers, telecom, automotive and industrial applications. It is also well suited for providing high power to large FPGAs, DSPs, or ASICs for consumer products. Other applications include voltage scaling for low power SOCS, as well as industrial control and power management systems.

The principle of operation of the IR3087MTR synchronous buck regulator controller is based on the Pulse Width Modulation (PWM) technique. PWM is a method of efficiently cutting up the load current and thus overcoming the problems of output voltage regulation with an analog linear regulator, such as output voltage accuracy and stability. In a synchronous buck converter, the PWM controller is used to control the switching elements in order to regulate the output voltage. The internal compensation network is used to adjust the converter gain, stability and transient response to reach the desired output voltage and current. The adaptive voltage scaling feature reduces energy consumption when there is a slow load change, and enables the buck regulator to maintain a constant output voltage.

In conclusion, the IR3087MTR synchronous buck regulator controller is a high performance, reliable power management solution for applications requiring fast transition times and excellent voltage and current regulation. It offers many advantages such as better efficiency, high utilization efficiency and lower component count to reduce total system cost, as well as adaptive voltage scaling and other features to ensure a robust and reliable system operation.
