LT3507AEFE#TRPBF

Overview

The LT3507AEFE#TRPBF is a power management IC featuring three synchronous buck converters and one low-dropout linear regulator. It operates with an input voltage range of 4V to 36V. The device provides four non-isolated outputs: Output 1 delivers up to 2.7A, while Outputs 2 and 3 provide up to 1.8A each. The switching frequency ranges from 900kHz to 1.1MHz. It is housed in a 38-lead TSSOP package with an exposed pad.

Feature Summary

Integrates three high-efficiency current-mode buck regulators and one LDO for multi-rail power distribution
Includes integrated power sequencer with independent run, track/soft-start, and power-good indicators
Supports ceramic output capacitors to minimize system component count and cost

Applications

Industrial automation control systems requiring multiple regulated voltages
Communication base station power management units
Automotive electronics with strict thermal and efficiency requirements
Distributed power supply architectures

Procurement Notes

Verify the specific suffix FE indicates the TSSOP-EP package configuration when sourcing. Confirm the AE grade meets the required -40°C to 125°C operating temperature range for your application environment. Ensure compatibility with the 38-pin footprint during PCB layout review.

Selection Notes

Select this component when a single IC solution is needed to generate three distinct buck rails and one LDO rail from a wide input voltage range. It is suitable for designs prioritizing board space reduction through integrated sequencing capabilities. Consider the 38-TSSOP-EP package constraints for thermal dissipation and trace routing.

Part Context

This part belongs to the LT3507 family of quad-output power management ICs designed for complex power distribution networks. It consolidates multiple discrete regulators into a single compact package, simplifying design complexity. The family supports various packaging options including QFN and TSSOP variants for different thermal and spatial needs.

Replacement Considerations

LT3507EFE#PBF is a tube-packaged equivalent within the same functional family. LT3507AHFE#TRPBF offers automotive-grade qualification with extended temperature limits.
