A8591KEJTR-J-1 is a DC-DC switching regulator power management IC from Alpha & Omega Semiconductor that combines advanced features and integrates over-voltage protection and reverse battery protection. This power management IC is well-suited for multiple end markets including consumer, communications, and transportation applications.
This DC-DC switching regulator IC has a wide range of features, including low-noise operation, low-dropout voltage, and high-current capability. It can also support high power up to 15A. The regulator can be switched between fixed voltage and programmable voltage modes, and the four-mode operation provides both efficiency and flexibility.
The A8591KEJTR-J-1 features an adjustable >3V to 28V input voltage range and an output voltage range of 0.9V to 5.5V. The operating temperature range is -40°C to +85°C for automotive and industrial applications. The power management IC also features a low quiescent current of 6uA, making it suitable for battery-powered applications.
This power management IC has a wide range of applications, such as in battery-powered devices, notebook and desktop PCs, digital cameras, portable audio players, and automotive and industrial applications.
Working Principle
The A8591KEJTR-J-1 DC-DC switching regulator IC works by controlling the on and off states of the switches that regulate the current flow in the circuit. The switched-mode power supply (SMPS) is made up of an inductor, capacitor, and two switches.
The two switches are the power switch, which is responsible for switching the power from the source to the inductor, and the ‘feedback’ switch, which is connected to the output of the circuit. When the power switch is on, current is supplied to the inductor and stored in the magnetic field. When the power switch is off, the energy is released and the current is forced through the feedback switch and into the load. This causes the power output to change with the on/off states of the power switch and the feedback switch.
The control circuitry of the A8591KEJTR-J-1 monitors the output voltage and dynamically adjusts the switching frequency and duty cycle of the switches in order to keep the output voltage at the desired level. The output voltage of the power supply is regulated by a feedback loop in order to maintain the desired output voltage.
The A8591KEJTR-J-1 is designed to provide high-efficiency DC-DC switching at high current loads. The power management IC is also designed to provide protection against over-voltage, over-current, and reverse battery conditions.
The A8591KEJTR-J-1 is an advanced power management IC that is well-suited for applications in the consumer, communications, and transportation markets. It features low-noise operation, low-dropout voltage, and high-current capability. With its adjustable input voltage, programmable voltage mode, and multiplemode operation, the A8591KEJTR-J-1 is a versatile and reliable choice for powering multiple end markets.
