LT3433EFE#TRPBF

Overview

The LT3433EFE#TRPBF is a high-voltage DC/DC converter from Analog Devices that provides both step-up and step-down regulation using a single inductor. It operates over an input voltage range of 4V to 60V, delivering an adjustable output between 3.3V and 20V with a maximum current of 0.9A. The device utilizes a 16-pin TSSOP EP package and functions as a switching regulator.

Feature Summary

• Provides simultaneous step-up and step-down regulation capabilities using a single inductor topology
• Operates within a wide input voltage range suitable for high-voltage applications
• Delivers adjustable output voltage levels with defined current capacity

Applications

• High-voltage DC/DC conversion systems
• Power supply designs requiring buck-boost functionality
• Industrial equipment power management

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches LT3433EFE#TRPBF exactly to avoid confusion with lead-free or non-tray variants. Cross-reference datasheets for electrical specifications before integration.

Selection Notes

Select this component when a single-inductor solution is required for both stepping up and down voltages. Consider the 4V to 60V input range and 0.9A output capability against load requirements. Evaluate the 16-pin TSSOP EP package constraints for PCB layout and thermal management needs.

Part Context

This part belongs to the LT3433 series of automatic high-voltage DC/DC converters. It is designed to simplify power architecture by combining buck and boost functions into one integrated circuit, reducing component count compared to discrete solutions.

Replacement Considerations

LT3433EFE#PBF is a verified alternative offering identical electrical characteristics but in tube packaging instead of tape-and-reel.
