LT3761EMSE-1#PBF

LED Driver IC Overview

The LT3761EMSE-1#PBF is a DC/DC controller designed for high-efficiency boost LED driving applications. It operates with an input voltage range of 4.5 V to 60 V and supports output currents up to 1 A. The device features internally generated PWM dimming, enabling precise brightness control with ratios up to 25:1. It functions as both a constant-current source and a constant-voltage regulator, suitable for automotive headlamp systems. The component is housed in a 16-lead MSOP package and operates within a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Internally generates PWM waveforms for accurate dimming without external timing components
• Operates as a constant-current source and constant-voltage regulator
• Supports multiple topologies including Boost, Buck, Buck-Boost, Flyback, and SEPIC

LED Driver IC Applications

• Automotive headlamp LED drivers
• High-voltage LED lighting systems
• Constant-current LED regulation circuits

LED Driver IC Procurement Notes

Verify the exact part marking matches LT3761EMSE-1#PBF. Confirm the manufacturer is Analog Devices Inc. Check the package type is MSOP-16. Ensure the suffix #PBF indicates lead-free compliance. Validate the datasheet revision against official Analog Devices documentation.

LED Driver IC Selection Notes

Select this component when internal PWM generation is required to simplify design. It is suitable for applications needing wide input voltage ranges up to 60V. Consider thermal performance in the MSOP-16 package for high-power designs. Verify compatibility with required LED string voltages and current settings.

LED Driver IC Part Context

This part belongs to the LT3761 family of LED controllers. It is specifically the -1 variant which includes internal PWM generation capabilities. The EMSE designation indicates the extended temperature grade and MSOP-16EP package. The #PBF suffix denotes RoHS compliance and halogen-free construction.

LED Driver IC Replacement Considerations

LT3761IMSE-1#PBF is a verified substitute offering identical functionality in the same package. LT3761EMSE#PBF is available but lacks the internal PWM generation feature found in the -1 variant.
