ADP2147ACBZ-130-R7 is a synchronous buck switching voltage regulator that utilizes adaptive voltage positioning (AVP) technology. It is part of the ADP21xx family from Analog Devices and is specifically designed to control Voltage regulators of different sizes and types. It is the ideal solution for applications requiring high efficiency and precision voltage regulation. The AVP technology enables the ADP2147ACBZ-130-R7 to remain tightly synchronized to the input voltage in order to maintain optimal output power. The regulator also offers a high level of flexibility as it supports both dynamic and static voltage positioning input modes. Additionally, it can be operated in switching mode as well as constant frequency mode.

The ADP2147ACBZ-130-R7 can provide both linear and [switch mode] voltage regulation to provide output up to 32.5V at 300mA. The maximum output current of the regulator is determined by the external MOSFET design and the selectable output voltage range is adjustable from 10V to 27V. The device also features short circuit protection, load current sensing, under-voltage protection, over-voltage protection, over-temperature protection, and output ripple control.

The ADP2147ACBZ-130-R7 is ideal for applications that require a wide operating temperature range such as solar cell, portable computing, digital cameras, and other mixed-power applications. The regulator is also well-suited for powering complex devices and systems such as LED arrays, LED signs, and microcontrollers. As such, it provides the reliability and flexibility necessary for a wide range of applications.

The ADP2147ACBZ-130-R7 functions through the use of a Buck-Boost topology. The Buck-Boost topology converts an input DC voltage into an output DC voltage with a different magnitude and voltage polarity. This process is achieved by utilizing two metal-oxide-semiconductor field-effect transistors (MOSFETs) to create a feedback loop. When the input voltage is lower than the output voltage, the MOSFET switches adjust the voltage output up and when the input voltage is higher, the MOSFET switches adjust the voltage output down. Consequently, the ADP2147ACBZ-130-R7 is able to maintain both a precise and efficient output voltage while also protecting the load from voltage and current fluctuations.

In addition to the Buck-Boost topology, the device employs the AVP technology. The AVP technology enables the regulator to operate at higher efficiency levels, while also providing greater control. The device is capable of dynamic voltage positioning, which compensates for voltage drops due to load currents, as well as static voltage positioning, which maintains a constant output voltage throughout the operating temperature range. Lastly, the device utilizes a low-ripple switching scheme, allowing it to provide a clean output voltage, free of unwanted noise.

The ADP2147ACBZ-130-R7 is an efficient and precise voltage regulator that is ideal for applications requiring a wide operating temperature range and precise voltage regulation. Its versatile design, featuring AVP technology, Buck-Boost topology, and remote sensing capabilities, make it an ideal solution for a wide range of applications.
