LT8616IFE#PBF

Overview

The LT8616IFE#PBF is a dual synchronous monolithic step-down switching regulator manufactured by Analog Devices Inc. It features an input voltage range of 3.4V to 42V and provides two independent adjustable output channels. Each channel supports up to 2.5A of continuous output current, allowing for a combined maximum output capability of 5A. The device operates with a fixed switching frequency of 2.05MHz or allows external synchronization from 100kHz to 3MHz. Quiescent current consumption is 6.5µA when both channels are enabled. The component is housed in a 28-lead TSSOP package with an exposed thermal pad.

Feature Summary

Dual-channel architecture providing independent control over two separate output rails
Integrated Silent Switcher topology designed to minimize electromagnetic interference radiation
Low quiescent current operation ensuring high efficiency during light load conditions
Synchronous rectification structure utilizing internal power switches for improved performance

Applications

Automotive infotainment systems requiring isolated power domains
Industrial distributed power architectures needing multiple regulated voltages
On-board charger circuits within electric vehicle powertrains
Telecommunications infrastructure equipment requiring efficient DC-DC conversion

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required packaging and temperature ratings. Confirm that the automotive-grade qualification aligns with target application standards. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Evaluate the total output current requirements to ensure neither channel exceeds its 2.5A limit under peak load conditions. Consider the thermal management capabilities of the PCB layout due to the exposed pad design. Assess whether the fixed 2.05MHz frequency optimizes the balance between component size and noise performance for the specific system environment.

Part Context

This component belongs to the LT8616 family of dual synchronous buck regulators. It shares architectural similarities with other devices in the series but offers distinct dual-output capabilities compared to single-channel variants. The device integrates advanced switching technology to deliver high efficiency in compact form factors suitable for space-constrained designs.
