LT7101IUHE#PBF

Overview

The LT7101IUHE#PBF is a synchronous step-down regulator from Analog Devices Inc., designed for high-voltage applications. It operates with an input voltage range of 4.5V to 105V and delivers up to 1A of output current. The device features a fixed switching frequency of 1MHz, ensuring efficient power conversion with low electromagnetic interference. It offers adjustable output voltages starting from 1V, housed in a compact 36-lead WFQFN package suitable for surface mount assembly.

Feature Summary

Integrated synchronous rectification for enhanced efficiency
Low EMI design optimized for noise-sensitive environments
Wide input voltage capability for industrial flexibility

Applications

Industrial automation control systems
High-voltage battery-powered equipment
Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix and tape/reel specifications against the official datasheet before ordering. Ensure thermal management requirements are met for the QFN package. Confirm that the operating temperature range aligns with the intended application environment to guarantee long-term reliability and performance stability.

Selection Notes

Select this component when a wide input voltage range exceeding standard 48V or 60V limits is required. It is suitable for designs needing a fixed 1MHz frequency to minimize external component size. Consider the 1A current limit and thermal dissipation capabilities of the 36-lead package for the specific load profile.

Part Context

This part belongs to the LT7101 series of high-voltage synchronous buck regulators. It shares functional similarities with other Analog Devices high-voltage PMICs but is distinct in its 105V input rating and 1A output capability. The series targets applications requiring robust power conversion in electrically noisy or high-voltage industrial settings.
