LT8616EFE#PBF

Overview

The LT8616EFE#PBF is a dual synchronous monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 5.8V to 42V and provides two independent output channels. The device supports output voltages of 2.5V and 5V, delivering up to 2.5A at 2.5V and 1.5A at 5V. It features a fixed switching frequency of 2.05MHz and consumes only 6.5µA of quiescent current with both channels enabled. The component is housed in a 38-lead TSSOP package.

Feature Summary

Dual-channel synchronous buck topology for independent power rail generation
High-speed operation with a fixed 2.05MHz switching frequency
Ultra-low quiescent current consumption of 6.5µA when both channels are active
Integrated soft-start functionality to limit inrush current during startup

Applications

Industrial distributed power systems requiring dual isolated rails
Telecommunications infrastructure equipment
Automotive electronics applications
Point-of-load regulation for digital signal processors

Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance before ordering. Confirm the 38-lead TSSOP package dimensions match your PCB footprint requirements. Ensure the input voltage range of 5.8V to 42V aligns with your system supply specifications. Check for any alternative packaging options if reel quantities are required instead of tubes.

Selection Notes

Select this component when dual output buck conversion is needed within a 42V input limit. The 2.05MHz frequency allows for smaller passive components compared to lower frequency alternatives. Consider thermal management requirements given the high current capabilities of 2.5A per channel. Verify that the 6.5µA standby current meets your system's low-power sleep mode requirements.

Part Context

This part belongs to the LT8616 family of dual synchronous step-down regulators. It shares architectural similarities with other high-voltage buck converters but is distinct in its dual-channel configuration and specific 2.05MHz operating frequency. The device is designed for applications requiring compact solutions with multiple regulated outputs from a single high-voltage source.
