LTC3452EUF#PBF

LED Driver IC Overview

The LTC3452EUF#PBF is a multi-output LED driver IC from Analog Devices Inc., housed in a 20-QFN (4x4 mm) package. It integrates a current-mode boost controller with six-channel LED drivers, designed for applications requiring step-up and step-down regulation. The device supports output currents of 25mA and 150mA, featuring dimming capabilities and a fixed-frequency architecture suitable for display backlights and camera flash systems.

LED Driver IC Feature Summary

• Integrates a current-mode boost controller with multiple LED driver channels
• Supports both step-up and step-down DC-DC regulation topologies
• Enables precise dimming control for display and lighting applications

LED Driver IC Applications

• Display backlighting systems
• Camera flash circuits
• Indicator lighting

LED Driver IC Procurement Notes

Verify the specific suffix #PBF to confirm lead-free compliance and tube packaging status. Confirm the 20-QFN pinout matches the target PCB footprint. Ensure input voltage ranges align with the integrated boost controller specifications before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a single IC solution is required for driving multiple LEDs with mixed current requirements. The integrated boost topology simplifies design for battery-powered devices where input voltage may vary below or above LED forward voltage drops.

LED Driver IC Part Context

This part belongs to the LTC3452 series of LED drivers. It is distinct from the LTC3453, which handles four segments, and the LTC3458/LTC3459, which are single-output boost converters. The LTC3452 is specifically engineered for complex multi-segment backlighting needs.

LED Driver IC Replacement Considerations

Direct substitutes include other Analog Devices multi-channel LED drivers such as the LTC3453EUF#PBF for fewer segments. Verify pin compatibility and current ratings against alternative parts like the LTC3458EDE#PBF if only single-channel boost functionality is needed.
