It can be used in a wide variety of applications such as in battery powered devices, medical devices, consumer electronics, factory automation equipment, computers and automotive electronics.

Application Field

The LT8711EFE#TRPBF has a wide range of applications. It is suitable for applications requiring voltage ranges up to 3.5V or 8V power supplies with a maximum output current of up to 8A. Some of the typical application fields that can utilize the LT8711EFE#TRPBF include LED Lighting, DC/DC converters, secondary side regulation, multi-output and PoL converters.

Working Principle

The LT8711EFE#TRPBF is designed to control the power supply for applications that require precisely regulated power output. It integrates two synchronous self-driven gate drivers to control two external MOSFETs in synchronous rectification mode. The LT8711EFE#TRPBF utilizes current sense architectures and pulse-width modulation (PWM) modulation modes to achieve a tightly-regulated output voltage.

The synchronous self-driven gate drivers provide fast switching, excellent current regulation, and allow for extremely low switching losses. This results in an efficient design, which can achieve higher power densities and a greater power output than traditional Switched-Mode Power Supply (SMPS) designs.

Features

The LT8711EFE#TRPBF is highly integrated and enables the design of compact and cost-effective power supplies. It features an adjustable frequency range of up to 500kHz, a programmable external clock, overvoltage and undervoltage protection, an intermediate voltage reference, and an ultraviolet ( UV ) light monitoring window. In addition, the LT8711EFE#TRPBF is designed with integrated protection features, such as current limit protection, thermal shutdown, and over-temperature warning alerts.

The LT8711EFE#TRPBF is designed for applications that require clean, well-regulated, and efficient power management. It can also be used in distributed power applications, such as hot-swap controllers, redundant systems, and power distribution networks. It is highly compatible with other logic circuits and can easily be integrated into existing systems.
