LT3435IFE#PBF

Overview

The LT3435IFE#PBF is a monolithic buck switching voltage regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.3 V to 60 V and provides an adjustable output voltage. The device features a fixed switching frequency of 500 kHz and delivers up to 2.4 A of output current. It incorporates a low quiescent current of 100 µA and supports shutdown functionality. The component is housed in a 16-lead TSSOP-EP package and is rated for operation between -40°C and +125°C.

Feature Summary

Integrates a high-voltage capable power switch suitable for wide input voltage ranges
Utilizes current-mode control architecture for stable regulation
Includes a dedicated shutdown pin for power management

Applications

Industrial systems requiring high-voltage step-down conversion
Automotive electronics operating within specified thermal limits
General-purpose DC-DC power supply designs

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required input voltage levels and thermal dissipation requirements before integration. Cross-reference datasheet revisions to validate electrical characteristics and pinout assignments for the final design implementation.

Selection Notes

Select this component when a wide input voltage range up to 60 V is required alongside moderate output current capabilities. The integrated switch simplifies bill of materials compared to controller-based solutions. Evaluate thermal performance within the TSSOP-EP package constraints for the intended application environment.

Part Context

This part belongs to the LT3435 series of high-voltage step-down switching regulators. It is designed to replace older discrete solutions or lower-voltage regulators in applications where bus voltages exceed standard limits. The family focuses on integrating power switches to reduce external component count.
