ADP2380AREZ-R7: High-Efficiency, Synchronous, Step-Down DC-to-DC Regulator

The ADP2380AREZ-R7 is a state-of-the-art synchronous step-down, or buck, DC-to-DC regulator from Analog Devices Inc., designed to deliver high efficiency and performance for a wide range of applications. This regulator is capable of providing a continuous output current of up to 4 A, making it suitable for powering core voltages, I/O, and peripheral rails in various electronic systems.

With an input voltage range of 4.5 V to 20 V, the ADP2380AREZ-R7 is versatile enough to be used in conjunction with a variety of power sources, including standard 5 V, 12 V rails, and intermediate bus voltages. This flexibility makes it an excellent choice for industrial, communications, healthcare, and consumer electronics where reliability and efficiency are paramount.

The device features an adjustable output voltage from 0.6 V to 85% of the input voltage, allowing for precise regulation tailored to the specific needs of the application. The high efficiency of up to 95% minimizes power loss and helps in thermal management, a critical aspect in modern compact electronic devices.

The ADP2380AREZ-R7 incorporates a proprietary current-mode, fixed-frequency PWM control scheme that provides fast transient response and excellent loop stability. The regulator also offers a range of protective features including overcurrent protection (OCP), undervoltage lockout (UVLO), thermal shutdown (TSD), and a power good flag, ensuring the safety and reliability of the end application.

For ease of use, this regulator is available in a compact 16-lead QSOP package, denoted by the "-R7" suffix, which is suitable for space-constrained applications. The package is RoHS compliant and designed for surface mount technology (SMT), streamlining the manufacturing process and allowing for higher density PCB designs.

Whether you're designing power supplies for networking equipment, servers, telecommunications, or portable devices, the ADP2380AREZ-R7 from Analog Devices Inc. provides a robust, efficient, and flexible solution to meet your DC-to-DC conversion needs.
