LT3435EFE#TRPBF

Overview

The LT3435EFE#TRPBF is a high voltage, monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed 500kHz switching frequency and supports an input voltage range from 3.3V to 60V. The device integrates a 3A power switch and delivers an adjustable output voltage with a maximum continuous output current of 2.4A. It features a low quiescent current of 100µA and functions within an operating temperature range of -40°C to +125°C. The component is housed in a 16-lead TSSOP package with an exposed pad for thermal management.

Feature Summary

Integrates a high-efficiency 3A power switch within a monolithic buck topology
Supports wide input voltage ranges up to 60V for flexible system design
Includes Burst Mode operation to maintain high efficiency at light loads
Features current-mode control architecture for fast transient response

Applications

Industrial point-of-load regulation
Automotive electronics systems
Distributed power architectures
Battery-powered equipment requiring high input tolerance

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with required thermal dissipation standards for the TSSOP-EP package. Confirm RoHS compliance details directly with the supplier or manufacturer datasheet prior to procurement.

Selection Notes

Select this component when a high input voltage capability up to 60V is required alongside moderate current demands. The fixed 500kHz frequency allows for compact external component sizing compared to lower-frequency alternatives. Consider the exposed pad requirement for adequate thermal performance during high-current operation.

Part Context

This part belongs to the LT3435 series of high-voltage step-down regulators. It shares architectural similarities with other members of the family but differs in specific pinout configurations and thermal characteristics associated with the TSSOP package variant.
