ADP2139ACBZ-2.5-R7

PMIC (Power Management Integrated Circuit) is a type of integrated circuit that is used to implement a range of power management functions. It can also be used to control the switching elements of a DC-DC converter, which provides power regulation, voltage regulation, current regulation, or a combination of all three. A DC-DC switching regulator is a type of power management integrated circuit that is designed to regulate an input voltage by switching the input on and off in a regulated manner. One example is the ADP2139ACBZ-2.5-R7, a two-terminal adjustable regulator designed for a wide operating temperature range.

The ADP2139ACBZ-2.5-R7 is a hysteretic buck regulator that provides high-efficiency power conversion and provides fast transient response and excellent line and load regulation. It is a very compact, low-cost, single-channel regulator with a 1.2 V to 5.5 V output range. The device has fewer external components than a traditional buck converter and does not require external loop compensation components, making it ideal for space-constrained applications. The ADP2139ACBZ-2.5-R7 also has a wide operating temperature range. This ensures that the device is compatible with a range of temperature environments, including those operating in extreme conditions.

The ADP2139ACBZ-2.5-R7 is designed to switch at a frequency of between 1 kHz and 1.5 MHz, with an adjustable output current limit feature and low quiescent current consumption. The device has integrated protection features that protect against output overvoltage, overcurrent, and over temperature. The device also integrates a power saving feature which reduces quiescent power consumption when the application is lightly loaded by entering a low-power mode.

The ADP2139ACBZ-2.5-R7 is ideal for applications that require an efficient, reliable, and cost-effective power management solution. It is suitable for use in battery-powered, portable devices, as well as industrial and automotive systems. It can be used in a wide range of applications including RF power amplifiers, low-power radio transceivers, audio amplifiers, and embedded system power control.

The working principle of the ADP2139ACBZ-2.5-R7 is based on a hysteretic (bang-bang) control technique. The device switches the input voltage to regulate the output voltage by switching the input on and off in a regulated manner. The voltage at the input is compared with the reference voltage, which determines when the output needs to be turned on or off. When the input voltage exceeds the reference voltage, the output is switched off, and when the input voltage is below the reference voltage, the output is switched on. This regulated switching of the input-voltage provides an efficient and cost-effective power management solution.

The ADP2139ACBZ-2.5-R7 is a high-efficiency and cost-effective DC-DC switching regulator that provides power regulation and voltage regulation for a wide range of applications. With a wide operating temperature range, integrated protection features, and low quiescent power consumption, the ADP2139ACBZ-2.5-R7 is an excellent choice for efficient and reliable power management solutions.
