PMIC (Power Management Integrated Circuit) is a device used to regulate and control the flow of electricity in order to ensure optimal performance of electronic equipment. One type of PMIC device, called a DC-DC Switching Regulator (also known as DC-DC Buck Converter), is an incredibly versatile type of voltage regulator. The MIC2202-1.2BML-TR is a highly specified DC-DC switching regulator developed by Micrel, Inc. and is used in a wide variety of power regulation applications.

What Is a DC-DC Switching Regulator?

A DC-DC switching regulator, also called a “buck converter”, is an electrical circuit used to convert a fixed DC voltage input into a variable DC voltage output. It is capable of regulating the voltage of both high-power and low-power devices. The buck converter is ideal for applications that require high efficiency and precise power regulation, and it has become increasingly popular due to its simple and efficient design.

Features of MIC2202-1.2BML-TR

The MIC2202-1.2BML-TR is a DC-DC switching regulator that is specially designed to provide unprecedented level of control, flexibility, and accuracy. It has a wide input voltage range of 4.5 V to 27 V and is capable of providing a regulated output voltage 0.8 V to 24 V. This regulator features excellent load and line regulation, fast transient response, and low output voltage ripple. It also has a proprietary active current sharing and thermal compensation circuit for increased accuracy in power delivery and temperature control.

The MIC2202-1.2BML-TR requires very minimal external components for operation, and uses a highly integrated design that ensures optimal efficiency. It also supports an adjustable soft-start feature as well as a power-good flag indication, allowing users to be informed of power supply status. The device also has built-in thermal protection that will shut down the regulator when the ambient temperature exceeds a certain value for safety.

Application Field and Working Principle

The MIC2202-1.2BML-TR is widely used in a variety of energy management applications, including LED drivers, portable electronics, automotive systems, and medical devices. It has a wide operating temperature range of -40 to +85°C and is highly reliable with a guaranteed output accuracy of ±1.5%, making it ideal for applications that demand precise power delivery.

The MIC2202-1.2BML-TR is a synchronous buck regulator with a constant frequency PWM control. It takes an input voltage and steps it down to a lower output voltage using power MOSFETs that switch at a fixed frequency. The output voltage is regulated and controlled by a feedback loop which reduces the duty cycle of the MOSFETs when the output voltage increases, and increases it when the output voltage decreases. This ensures the output voltage remains within the specified range.

The MIC2202-1.2BML-TR is designed to be very efficient and reliable, making it a perfect choice for many power regulation applications. With its advanced features and excellent performance, this regulator ensures optimal performance and energy savings while providing precise power regulation with guaranteed accuracy.
