The AS13985F26_ EK_ST evaluation board is an integrated linear power supply designed for power management applications. It is an efficient, easy-to-use and high-level management system solution for development and evaluation of linear voltage regulator applications. It offers a wide range of features, from enhanced design flexibility to optimized energy efficiency and cost saving solutions.

The AS13985F26_ EK_ST evaluation board implements the AS13985F26-ST linear voltage regulator, which is a highly versatile, cost-effective and efficient solution for applications such as power conditioning and regulation, charging control, server and datacenter power conversion, and motion control systems. This regulator can provide tight regulation of the output power, and achieves very high efficiency even at low output power levels. It also supports a wide input voltage range from 6V to 28V, which can be used in multi-rail designs with different output voltages.

The linear voltage regulator\'s working principle is based on the voltage divider theory. The input voltage is divided between two resistors- the lower one being connected to the reference voltage, and the higher one being connected to the output voltage. The output voltage is then regulated by changing the resistance of one of the resistors, thus changing the voltage difference between the two resistors. The output voltage can be regulated by changing the resistance of either the lower or the higher resistor.

The AS13985F26_ EK_ST evaluation board contains an MCU-based power supply controller, a multimedia codec and an audio converter. It also contains two LCD panels, one for the voltage regulator settings and the other for displaying output measurements. The evaluation board also has several options for interfacing with other components, such as an external pre-regulator, an external boost controller and an external XTAL. In addition, the board includes an SPI, I2C and UART interface, as well as an onboard configurable LTDC (Liquid Crystal Tunable Display Controller).

The linear voltage regulator requires a stable power supply in order to achieve maximum efficiency. The AS13985F26_ EK_ST evaluation board provides this feature by utilizing an advanced low ESR power supply solution. The integrated MCU-based power supply controller can be configure to manage and balance up to 6 different voltage rails, which allows greater flexibility in power management. The board is also designed to operate with up to 20W of total power draw, making it suitable for high power applications.

In addition, the AS13985F26_ EK_ST evaluation board includes an adjustable current-limit circuit, which provides protection against over-current and over-voltage conditions, as well as a thermal protection system to protect the device from excessive heat. The adjustable current-limit circuit allows the user to set a maximum allowed output current, and the thermal protection system monitors the temperature of the power supply in order to prevent overheating.

The AS13985F26_ EK_ST evaluation board is an efficient, easy-to-use, and high-level management system solution for applications that require a linear voltage regulator. It offers a wide range of features, and is suitable for use in a variety of applications, from power conditioning and regulation, to charging control, server and datacenter power conversion, and motion control systems. The advanced power supply controller, adjustable current limit circuit, and thermal protection system provide reliable power supply protection, and the onboard codec and audio converter allow for efficient audio processing.
