LT3472EDD#TRPBF

Overview

The LT3472EDD#TRPBF is a synchronous buck regulator featuring a fixed 1.5 MHz switching frequency. It supports an input voltage range of 2.7 V to 6 V and delivers up to 1 A output current. The device operates with a typical quiescent current of 100 µA. Output voltage is adjustable from 0.8 V to 5.5 V. It utilizes a DFN-8 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates two N-channel power switches for high-efficiency synchronous rectification
Combines Burst Mode operation with continuous conduction for optimized light-load performance
Includes internal compensation to minimize external component count
Features cycle-by-cycle current limit and thermal shutdown protection

Applications

Battery-powered portable electronics
Industrial control systems
Infotainment modules
Automotive sensor interfaces

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when placing orders. Confirm RoHS compliance status through official documentation. Ensure the DFN-8 footprint matches the PCB layout requirements. Cross-reference the datasheet revision to validate electrical characteristics against design specifications.

Selection Notes

Select this component for designs requiring a 1 A load capability with minimal standby power consumption. The fixed 1.5 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the input voltage source remains within the 2.7 V to 6 V operational window for reliable regulation.

Part Context

The LT3472EDD#TRPBF is a micropower synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It belongs to the LT3472 series, designed for applications requiring high efficiency and low quiescent current in compact form factors. The device integrates power switches and control circuitry into an 8-lead DFN package.
