概述

Description

The LT3482EUD#TRPBF is a product number for a specific type of integrated circuit (IC), manufactured by Analog Devices. It is a high-efficiency step-up DC/DC converter typically used in power supply circuits to increase voltage from a lower input voltage to a higher output voltage. The device is designed with an internal switch, Schottky diode, and compensation circuitry, providing a compact solution for power conversion applications. It features low quiescent current, over-current protection, and can handle up to 36V on the output with a wide input voltage range. These features make it suitable for battery-powered devices, portable electronics, and other applications requiring efficient voltage stepping. The "EUD" in the part number indicates the package type, which is a 10-lead DFN (dual flat no-leads) package, and "#TRPBF" implies it is lead-free and available in tape and reel for automated handling.

Features

The LT3482EUD#TRPBF is a micropower DC/DC converter with several key features:
1. Efficiency: It offers high efficiency over a wide range of output currents, making it suitable for battery-powered applications.
