LT7101HUHE#TRPBF

Overview

The LT7101HUHE#TRPBF is a synchronous buck regulator from Analog Devices, designed for high-voltage input applications. It features an integrated 2.3A switch and supports input voltages up to 105V. The device operates with a fixed switching frequency of 1.2MHz, enabling the use of small external components. It includes programmable soft-start and current limit functions to protect against overload conditions. The regulator provides a stable output voltage with low ripple, suitable for powering sensitive downstream circuitry in industrial and automotive environments.

Feature Summary

• Integrated high-voltage synchronous buck architecture supporting inputs up to 105V
• Fixed 1.2MHz switching frequency for compact passive component selection
• Built-in programmable soft-start and cycle-by-cycle current limiting
• Synchronous rectification for improved efficiency at light and heavy loads

Applications

• Industrial motor drives and control systems
• Automotive infotainment and sensor power supplies
• Distributed power architectures in telecom equipment
• High-voltage battery-powered portable devices

Procurement Notes

Verify the complete part number including suffixes such as #TRPBF for tape-and-reel packaging and lead-free compliance. Confirm the manufacturer source is authorized to ensure authenticity. Check datasheet revisions for any updates to electrical characteristics or pinout configurations before finalizing procurement specifications.

Selection Notes

Select this component when input voltages exceed standard 42V limits but remain below 105V. Evaluate thermal performance based on expected load current and ambient temperature. Ensure the chosen inductor value supports the 1.2MHz frequency without saturating. Verify that the required output voltage range aligns with the internal feedback network capabilities.

Part Context

This part belongs to the LT7101 family of high-voltage synchronous buck regulators. It shares architectural similarities with other LT series converters but is distinct in its 105V input rating and 2.3A output capability. It complements lower voltage regulators like the LT8607 by addressing higher input voltage requirements in compact form factors.
