LT7101IUHE#TRPBF

Overview

The LT7101IUHE#TRPBF is a synchronous step-down regulator from Analog Devices, designed for high-voltage applications with an input voltage range up to 105V. It integrates a 1A power switch and delivers a regulated output current of 1A. The device operates at a fixed switching frequency of 1.2MHz and features low EMI characteristics to minimize electromagnetic interference in sensitive environments. It provides adjustable output voltage control and includes comprehensive protection mechanisms such as thermal shutdown and current limiting. Packaged in a compact 16-lead SSOP, it supports operation over an extended temperature range.

Feature Summary

• Integrates a high-voltage 1A synchronous buck converter capable of handling input voltages up to 105V
• Features low EMI design architecture to reduce electromagnetic interference emissions
• Includes built-in thermal shutdown and current limit protection for enhanced reliability

Applications

• Industrial automation systems requiring isolated or non-isolated DC-DC conversion
• Automotive electronics operating within high-voltage bus architectures
• Telecommunications infrastructure power distribution networks

Procurement Notes

Verify the exact suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the 'I' grade designation matches your required industrial temperature specifications. Ensure compatibility with your PCB footprint for the 16-lead SSOP package. Cross-reference the datasheet revision date to ensure all electrical parameters align with your design requirements before finalizing procurement.

Selection Notes

Select this component when a high input voltage capability exceeding standard 40V regulators is necessary. The 1A output current suits moderate load applications where efficiency and size are critical. Consider the 1.2MHz switching frequency for balancing component size against noise performance. Evaluate the low EMI feature if the application operates near sensitive analog circuits or communication interfaces.

Part Context

This part belongs to the LT7101 family of high-voltage synchronous buck regulators. It shares core functionality with other variants differing primarily in temperature grades and packaging options. The series targets applications needing robust power conversion from high-voltage sources without external high-voltage switches.

Replacement Considerations

LT7101EUHE#TRPBF: Lower temperature grade variant. LT7101HUHE#TRPBF: Higher temperature grade variant.
