The A8281SLBTR is classified as a special purpose Voltage Regulator within the PMIC (Power Management Integrated Circuit) category. This regulator is designed to provide regulated output voltages across a wide range of applications. The A8281SLBTR is a non-buffered, single output voltage regulator which uses Linear Technology\'s proprietary "VCR" (variable current Regulation) technology. This technology is ideal for use in applications where high efficiency, low output noise, and high power density are desired.

The A8281SLBTR is primarily used for high speed regulation of DSP/FPGA power supply. It is capable of providing a wide input voltage range from 6.0V to 12.6V, and a maximum output current of 18A. The A8281SLBTR has many unique features such as an adjustable switching frequency, dynamic voltage scaling, and a high accuracy voltage regulation. There are also two packages available, the MPQ28 and the DCQ28, and both are RoHS and REACH compliant.

The working principle of the A8281SLBTR is based on its innovative VCR technology. The regulators use a combination of linear and switch mode techniques to achieve a high power efficiency while still providing a low output noise. At start up, the integrated primary control loop activates the linear regulator, which runs in continuous conduction mode (CCM). The linear regulator is then able to accurately regulate the output voltage, while the switching regulator is used to supply the load current. When the current limit is reached, the linear regulator is shut off and cycle-by-cycle current control is used. The A8281SLBTR also features a dynamic voltage scaling function to provide an additional 10% margin beyond the nominal voltage setting. This feature can also be used to reduce power consumption in light load conditions.

The A8281SLBTR is a highly integrated, cost effective solution for applications such as digital signal processors, FPGAs, and other digital logic systems. Its high power efficiency, low output noise, and high switching frequency make it an ideal choice for these types of applications. It is RoHS and REACH compliant and has two packages available, providing flexibility for design and layout. The A8281SLBTR also offers an adjustable switching frequency, current limit protection, and dynamic voltage scaling to provide additional flexibility in power supply design.
