ISL8112IRZ-T is a 3A high efficiency, dual channel synchronous step-down DC/DC regulator. It can provide consumers with a regulated output voltage of up to 12V, while also providing a maximum step-down efficiency of 97%. This is a fully integrated solution that includes a built-in power distribution switch and a simple low-noise output filter. The ISL8112IRZ-T is designed for applications such as automotive, industrial, and communications systems, where power-efficient solutions are required.The ISL8112IRZ-T operates by employing an integrated high-current synchronous buck controller, which outputs two regulated voltages, one for each channel. The two output voltages are adjustable by steering two external high-side switches in order to create two buck paths from a single input voltage. By utilizing high-side switches, the ISL8112IRZ-T avoids any direct connection of the low-side switches to the power supply and ensures fast transient response and operation at light load without sacrificing efficiency.The ISL8112IRZ-T also features several unique features that extend its usefulness even further. It provides a low-dropout shutdown mode that keeps power consumption under control while maximizing the system’s efficiency. The application’s maximum start-up current is also controlled, providing an enhanced system design flexibility. The detailed output voltage tracking feature allows the use of multiple virtual output pins for load sharing, which provides increased flexibility for the application.The ISL8112IRZ-T also features an integrated fast response soft-start circuit and operation of the integrated error amplifier, which allows for better system transient operation. The device also features phase loss protection and under voltage lockout, both of which provide additional protection and stability to the system.The ISL8112IRZ-T is a versatile and power efficient solution for automotive, industrial, and communications systems. It features an adjustable output voltage range of up to 12V and a maximum efficiency at 97%. The device is capable of providing two regulated outputs, fast transient response, low-dropout shutdown mode, integrated error amplifier and phase loss protection. Combined with its unique features, the ISL8112IRZ-T is an excellent solution for efficient power systems.
