LT3760IFE

LED Driver IC Overview

The LT3760IFE is an 8-channel LED driver IC manufactured by Analog Devices Inc. It functions as a step-up DC/DC controller capable of driving up to 45V of LEDs. Each channel integrates an accurate current sink rated for 100mA. The device supports PWM dimming and operates within a supply voltage range of 6V to 60V, with output voltages reaching 55V. It utilizes a 28-TSSOP-EP package and features a switching frequency range of 200kHz to 1MHz. The component is designed for surface mount installation and operates at junction temperatures between -40°C and 125°C.

LED Driver IC Feature Summary

• Integrates eight independent high-side current sinks for precise LED channel control
• Built-in step-up DC/DC controller eliminates external boost converter requirements
• Supports analog and PWM dimming methods for brightness adjustment
• Includes internal compensation and protection features for stable operation

LED Driver IC Applications

• LCD backlight drivers for portable devices
• High-brightness LED lighting systems
• Automotive interior lighting applications
• Industrial display illumination modules

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence when sourcing. Confirm the 28-TSSOP-EP package variant matches your PCB footprint requirements. Check the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions prior to final design implementation.

LED Driver IC Selection Notes

Select this component when designing multi-channel LED arrays requiring a single controller solution. Ensure the input voltage range aligns with the system power supply. Consider thermal management needs due to the integrated current sinks. Verify that the required LED forward voltage sum does not exceed the 45V capability of the boost stage.

LED Driver IC Part Context

This part belongs to the LT3760 family of LED drivers from Analog Devices. It is distinct from the LT3763, which is a buck topology controller. The LT3760 specifically addresses applications requiring voltage boosting to drive series LED strings. It shares the TSSOP-EP package form factor with other members of the company's PMIC portfolio.

LED Driver IC Replacement Considerations

Direct substitutes include the LT3760IFE#TRPBF for tape-and-reel packaging. Cross-reference with other 8-channel boost LED drivers if pin compatibility is not required. Verify functional equivalence regarding current sink accuracy and dimming signal requirements before substitution.
