LT3435IFE#TRPBF

Overview

The LT3435IFE#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.3 V to 60 V and delivers up to 2.4 A of output current. The device features a fixed switching frequency of 500 kHz and maintains a low quiescent current of 100 µA. It provides an adjustable output voltage within a single-channel configuration. The component is housed in a TSSOP-EP-16 package and supports operation across a temperature range from -40°C to +125°C.

Feature Summary

• Integrates a high-voltage power switch capable of handling inputs up to 60 V
• Includes internal compensation for simplified external component requirements
• Features cycle-by-cycle current limit protection for robust operation

Applications

• Industrial control systems requiring isolated or non-isolated power conversion
• Automotive electronics operating on 12 V or 24 V bus architectures
• Distributed power supply architectures in telecommunications equipment

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the required temperature grade and package variant. Cross-reference the manufacturer's latest datasheet revision to validate pinout compatibility and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require high input voltage tolerance combined with moderate output current capabilities. The integrated power switch eliminates the need for external MOSFETs, reducing board space. Consider the 500 kHz switching frequency for balancing efficiency and passive component size. Verify thermal performance requirements given the TSSOP-EP-16 package constraints under maximum load conditions.

Part Context
