The AP1084K25G-13 is a monolithic linear high-current DC-DC regulator designed to provide a regulated 12V supply at up to 25A. The device employs a synchronous rectifier followed by a linear regulator to achieve a high efficiency, low noise output over a wide range of load levels.

The device is capable of producing a well regulated 12V output at up to 25A and is designed to operate with a wide input voltage of 4.5V to 20V. Additionally, the AP1084K25G-13 features a low-minimum input voltage of 4.5V, providing the ability to operate at low input voltages. This allows the device to be used in a variety of applications where a regulated voltage is needed but the available input voltage may vary significantly.

In addition to its high-current capability, the AP1084K25G-13 features a wide variety of other features to ensure performance and reliability. These features include a low quiescent current for improved efficiency, an adjustable voltage reference to allow output voltage adjustment, and a fast transient response to ensure stability. In addition, the device has built in protection circuitry to protect against over voltage, over current, and reverse polarity conditions.

The AP1084K25G-13 is commonly used in a variety of applications that require a regulated 12V supply without sacrificing performance. These applications include automotive, industrial, and medical devices. Common applications include solar inverters, medical imaging equipment, air conditioners, motors and fans, and power supplies.

The AP1084K25G-13 works by using a synchronous rectifier to convert the input voltage to an intermediate voltage and then uses a linear regulator to provide a well regulated output voltage. The synchronous rectifier uses a series of rectifying diodes arranged in pairs to allow the output voltage of the regulator to track the input voltage. This feature allows for high efficiency operation as well as providing a fast, low noise output. The linear regulator follows the output of the synchronous rectifier and provides a stable and regulated output voltage. The synchronous rectifier and linear regulator are controlled by a feedback loop that monitors the output voltage and adjusts the output of the regulator accordingly.

The wide input voltage range and high efficiency of the AP1084K25G-13 make it an ideal choice for applications requiring a regulated 12V supply. Its low quiescent current, adjustable voltage reference, and fast transient response provide the reliability and performance needed for rugged, high-current applications.
