LT3473AEDE#PBF

Overview

The LT3473AEDE#PBF is a high-efficiency, synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 36V and delivers up to 3A of output current. The device integrates two N-channel power switches and supports adjustable switching frequencies from 200kHz to 2MHz. Key electrical parameters include a quiescent current of 1.5mA, a shutdown supply current of 1µA, and a feedback reference voltage of 0.8V. It features cycle-by-cycle current limiting, thermal shutdown, and soft-start capabilities within a thermally enhanced 16-lead DFN package.

Feature Summary

Integrates dual N-channel power switches for high efficiency in compact designs
Supports wide input voltage ranges suitable for single-cell lithium-ion or multi-cell battery applications
Includes programmable frequency synchronization and phase shifting for multi-phase operation

Applications

Battery-powered portable equipment
Industrial control systems
Automotive electronics

Procurement Notes

Verify the specific suffix AEDE against official datasheets to confirm temperature grade and package type. Ensure RoHS compliance matches project requirements. Confirm availability status as distribution channels may vary. Validate pinout compatibility during PCB layout review.

Selection Notes

Select this component when designing space-constrained systems requiring high current density. Evaluate thermal performance based on ambient conditions and copper area. Consider external compensation components if operating at extreme frequencies. Verify input capacitor ratings against ripple current specifications.

Part Context

This part belongs to the LT3473 family of synchronous buck converters. It shares functional similarities with other members like the LT3473EFE but differs in package configuration. The family targets applications needing robust power management in small footprints.
