LT8616EFE#TRPBF

Overview

The LT8616EFE#TRPBF is a high-efficiency, high-speed dual synchronous monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with 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 total combined output capability of 5A. The device features a low quiescent current consumption of 6.5µA when both channels are enabled. It utilizes a fixed switching frequency of 2.05MHz and is housed in a 28-lead TSSOP package with an exposed pad.

Feature Summary

• Dual-channel synchronous buck topology providing independent adjustable outputs
• Ultra-low quiescent current consumption of 6.5µA with both channels active
• Integrated 2.05MHz fixed switching frequency for compact passive component sizing
• Wide input voltage range supporting 3.4V to 42V operation

Applications

• Industrial distributed power systems requiring dual rails
• Automotive infotainment and control module power distribution
• Telecommunications equipment powering mixed-signal circuits
• Embedded systems utilizing wide input voltage sources

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube packaging when sourcing components. Confirm that the manufacturer is Analog Devices Inc. or Linear Technology as appropriate for the production era. Ensure the part number matches the exact electrical specifications required for your design, particularly the 2.05MHz frequency and dual-channel configuration. Cross-reference the datasheet revision to ensure compatibility with your thermal and electrical requirements.

Selection Notes

Select this component when a dual-output solution is required from a single IC footprint to save board space. The 2.05MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the 42V maximum input rating for applications involving automotive loads or industrial bus voltages. Evaluate the thermal performance within the 28-lead TSSOP package against the expected load currents and ambient temperature conditions.

Part Context

The LT8616EFE#TRPBF belongs to the LT8616 family of dual synchronous step-down regulators. This series is designed for applications demanding high efficiency and low standby power consumption. The device integrates power switches, controllers, and protection features into a single monolithic structure. It serves as a power management solution for systems requiring multiple regulated voltages derived from a common input source.

Replacement Considerations

LT8616HFE#TRPBF offers identical electrical performance but is qualified for automotive applications.
