LT3430EFE#TRPBF

Overview

The LT3430EFE#TRPBF is a high-voltage, monolithic step-down DC/DC switching converter manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5 V to 60 V and delivers up to 3 A of output current. The device features a fixed 200 kHz switching frequency and supports adjustable output voltages starting from 1.219 V. Packaged in a 16-lead TSSOP with exposed pad for thermal enhancement, it functions as a buck or SEPIC converter. The component operates within a junction temperature range of 0°C to 125°C and includes shutdown functionality.

Feature Summary

Integrates a 3 A internal power switch for high-current capability in a compact form factor
Supports wide input voltage ranges suitable for various DC/DC conversion topologies
Utilizes a thermally enhanced package to manage heat dissipation effectively

Applications

DC/DC converters requiring compact space and wide input voltage ranges
High-voltage step-down power supply designs
Industrial equipment power management systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Ensure compatibility with the 16-TSSOP-EP footprint during PCB layout. Check for any recent product change notifications regarding material or design updates before finalizing procurement.

Selection Notes

Select this component for applications demanding high input voltage tolerance up to 60 V. The 200 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance of the exposed pad package for high-load scenarios. Verify that the required output voltage falls within the adjustable range supported by the external resistor network.

Part Context

This part belongs to the LT3430 series of high-voltage switching regulators. It is designed for versatile power conversion tasks where space is limited but high current is required. The series is known for integrating power switches and control logic into a single monolithic IC, simplifying the design process for engineers developing efficient power supplies.
