LT3942HUFD#TRPBF

LED Driver IC Overview

The LT3942HUFD#TRPBF is a synchronous buck-boost converter and LED driver from Analog Devices. It operates with an input voltage range of 3V to 36V and delivers up to 2A output current. The device supports switching frequencies between 300kHz and 2MHz, enabling flexible design options for various lighting applications. It features both analog and PWM dimming capabilities for precise light control. The component is housed in a 28-lead QFN package and is rated for operation across a temperature range of -40°C to 150°C.

LED Driver IC Feature Summary

• Synchronous buck-boost topology supporting wide input voltage ranges
• Integrated dual-mode dimming capability for analog and pulse-width modulation control
• Programmable switching frequency allowing synchronization or spread spectrum operation

LED Driver IC Applications

• General purpose lighting systems
• Automotive interior and exterior illumination
• Industrial high-bay lighting fixtures

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm availability status as supply may be limited or subject to factory order constraints. Ensure the operating temperature grade matches the environmental requirements of the final assembly. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

LED Driver IC Selection Notes

Select this component for designs requiring a single-stage solution for both regulation and LED driving. The buck-boost architecture accommodates battery discharge profiles without additional stages. Consider the thermal performance of the QFN package relative to the expected load current. Evaluate the external component count against board space limitations given the integrated switch design.

LED Driver IC Part Context

This part belongs to the LT3942 family of LED drivers designed by Analog Devices. It shares functional similarities with other members like the LT3942IUFD but differs in temperature grading and packaging options. The HUFD designation specifies the commercial/industrial temperature range and lead-free QFN package configuration within the broader product line.

LED Driver IC Replacement Considerations

LT3942HUFD#PBF is a verified alternative offering the same electrical specifications in a tray package instead of tape and reel.
