LT3596IUHG

LED Driver IC Overview

The LT3596IUHG is a 60V step-down LED driver featuring three independent 100mA output channels. It supports digital PWM dimming with a 10000:1 ratio at 100Hz and operates within a switching frequency range of 200kHz to 1MHz. The device provides precise current regulation for driving up to ten LEDs per channel. It is housed in a 52-lead QFN package and functions across an operating temperature range of -40°C to 125°C TJ.

LED Driver IC Feature Summary

• Integrates three independent 100mA constant current output channels for multi-string LED control
• Enables high-resolution digital PWM dimming with a 10000:1 contrast ratio
• Utilizes fast NPN current sources to drive multiple LEDs per channel efficiently

LED Driver IC Applications

• LED signage illumination systems
• Display backlighting applications
• General LED lighting fixtures

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., #PBF) against the manufacturer's official documentation to confirm RoHS compliance status, as historical records indicate variations between leaded and lead-free versions for this component family. Ensure the ordering part number matches the exact package type and thermal characteristics required for the target design.

LED Driver IC Selection Notes

Select this component when designing circuits requiring independent control of multiple LED strings from a single buck converter topology. It is suitable for applications demanding high dynamic range dimming capabilities without external microcontrollers for basic on/off or brightness control logic.

LED Driver IC Part Context

This part belongs to the Analog Devices LT3596 series of high-voltage LED drivers. It is designed to simplify the power management architecture for complex lighting arrays by integrating multiple regulated outputs into a single compact surface-mount package, reducing board space compared to discrete solutions.

LED Driver IC Replacement Considerations
