LT8620IUDD#TRPBF

Overview

The LT8620IUDD#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in a 16-lead QFN package. It supports an input voltage range of 3.4V to 65V and delivers up to 2A output current. The adjustable output voltage spans from 970mV to 64.75V. Key electrical parameters include a quiescent current of 2.5µA, a switch frequency range of 200kHz to 2.2MHz, and an operating temperature range of -40°C to +125°C.

Feature Summary

Integrates high-side and low-side power switches with all necessary control circuitry to minimize external component count.
Features ultra-low quiescent current consumption for efficient battery-powered operation.
Includes programmable soft-start and cycle-by-cycle current limit protection.

Applications

Industrial point-of-load regulation
Automotive electronics systems
Distributed power architectures

Procurement Notes

Verify the specific suffix 'IUDD' against official Analog Devices documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with the required thermal pad soldering process for the QFN package. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when a wide input voltage range up to 65V is required alongside compact size constraints. The integrated switches reduce bill-of-materials complexity compared to controller-based solutions. Evaluate the thermal performance requirements for the QFN package based on the expected load current and ambient conditions.

Part Context

This part belongs to the LT8620 family of high-voltage synchronous buck regulators. It shares core architectural features with other variants in the series but differs in package type and temperature rating. The family is designed for applications requiring high efficiency and low standby power in space-sensitive environments.
