LT3596EUHG#TRPBF

LED Driver IC Overview

The LT3596EUHG#TRPBF is a triple-output LED driver IC from Analog Devices, housed in a 52-QFN package. It operates with an input voltage range of 6V to 55V and supports PWM dimming. Each channel provides a regulated output current up to 100mA, suitable for high-brightness LED applications. The device integrates internal switches and functions as a buck converter topology. It operates within a junction temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Triple independent regulated LED driver outputs
• Supports analog and PWM dimming control
• Integrated open LED protection circuitry
• No microcontroller required for basic operation

LED Driver IC Applications

• Backlight systems
• Signage illumination
• High-brightness LED arrays

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the 'E' grade designation matches thermal requirements. Check current distributor availability as supply status may vary. Ensure the 52-QFN footprint matches the PCB design. Validate RoHS compliance documentation for the specific batch.

LED Driver IC Selection Notes

Select this component for designs requiring three isolated or common-anode LED channels from a single controller. The wide input voltage range accommodates various bus voltages. Consider the 52-QFN package size for space-constrained layouts. Evaluate thermal dissipation needs given the 125°C maximum junction rating. Compare against single-channel drivers if fewer outputs suffice.

LED Driver IC Part Context

This part belongs to the LT3596 series of LED drivers designed by Analog Devices. It is distinct from the LTC3865 and LTC3569 power management ICs listed in related data due to its specialized LED regulation function. The EUHG suffix denotes the specific QFN-52 package variant. It serves as a dedicated solution for multi-zone lighting control without external MCU intervention.
