LT3988IMSE#TRPBF

Overview

The LT3988IMSE#TRPBF is a dual-channel synchronous step-down DC/DC converter featuring an integrated 60V N-channel power switch. It supports an input voltage range from 4.1V to 60V with adjustable output voltages between 0.75V and 59.4V per channel. The device delivers up to 1A of continuous output current per channel and operates with a programmable switching frequency ranging from 250kHz to 2.15MHz. It utilizes a 16-lead MSOP package with an exposed thermal pad for efficient heat dissipation.

Feature Summary

• Dual independent synchronous buck channels providing flexible multi-rail power distribution
• Integrated high-voltage N-channel switches eliminating external component requirements
• Programmable switching frequency allows optimization for efficiency or transient response
• Low quiescent current operation enhances system efficiency during light load conditions

Applications

• Industrial automation controllers requiring isolated power rails
• Automotive infotainment and sensor node power management
• Telecommunications equipment powering logic and interface circuits
• Distributed power systems in harsh environmental conditions

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the IMSE designation corresponds to the industrial temperature grade (-40°C to +125°C junction temperature). Ensure compatibility with the 16-MSOP EP footprint during PCB layout. Cross-reference official Analog Devices documentation for RoHS compliance status prior to final procurement approval.

Selection Notes

Select this component when dual isolated outputs are required within a single package footprint. The 60V input rating suits applications with higher bus voltages. Consider the thermal performance of the MSOP package for high-current designs. Verify that the 1A per channel limit meets the total load requirements of the target application without exceeding thermal constraints.

Part Context

This part belongs to the LT3988 family of dual synchronous buck converters designed for high-voltage, space-constrained applications. It shares architectural similarities with other high-voltage regulators but distinguishes itself through dual-channel integration. The series targets industrial and automotive sectors where reliability and compact form factors are critical design parameters.

Replacement Considerations

LT3988EMSE#PBF: Identical functional specifications with tube packaging instead of tape and reel.
