LTC3454EDD#TRPBF

LED Driver IC Overview

The LTC3454EDD#TRPBF is a synchronous Buck-Boost DC/DC regulator designed as a high-current LED driver by Analog Devices Inc. It operates with an input voltage range of 2.7V to 5.5V and supports an oscillator frequency of 1MHz typical. The device integrates internal switches and provides configurable output current from 20mA to 150mA via external resistors, eliminating the need for microcontrollers. It features open/shorted LED protection and internal soft-start capabilities.

LED Driver IC Feature Summary

Synchronous Buck-Boost topology for flexible LED drive configurations
Integrated internal switches eliminate external power components
Configurable output current without requiring microcontroller control
Built-in protection against open and shorted LED conditions

LED Driver IC Applications

High current LED driving in portable devices
Battery-powered applications requiring wide input voltage ranges
Stand-alone LED illumination systems

LED Driver IC Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology. Ensure the part number matches the exact electrical specifications required for your design, particularly the 1A current capability and 1MHz switching frequency.

LED Driver IC Selection Notes

Select this component when a Buck-Boost topology is necessary to maintain regulation across varying battery voltages. It is suitable for designs requiring up to 1A LED current with minimal external component count. Consider the 1MHz frequency for smaller passive sizes compared to lower-frequency alternatives.

LED Driver IC Part Context

This part belongs to the LTC3454 series of PMIC LED drivers. It is manufactured by Analog Devices Inc., formerly Linear Technology. The EDD suffix denotes the QFN package type used for surface mount installation.
