LT3950JMSE#TRPBF

LED Driver IC Overview

The LT3950JMSE#TRPBF is a multitopology DC/DC converter designed for high-current LED driving. It integrates a 1.5A, 60V DMOS switch and supports external PWM dimming via a PMOS transistor. The device features an internal PWM generator that maps analog control signals to duty cycle. It operates with a minimum supply voltage of 3V and a maximum of 60V, providing an output voltage range starting at 1.2V. This component is packaged in a surface-mount format suitable for compact designs.

LED Driver IC Feature Summary

LED Driver IC Applications

• High current LED arrays
• LED backlight systems
• Moderate-power LED lighting solutions

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact JMSE package variant. Check RoHS compliance status as lead-free. Validate the datasheet version against the latest Analog Devices documentation to ensure accurate electrical specifications.

LED Driver IC Selection Notes

Select this component for applications requiring a single IC to handle multiple LED topologies. The integrated 60V switch allows for higher input voltage flexibility compared to lower-voltage alternatives. Consider the external PMOS requirement for dimming functionality. Evaluate the 1.5A current limit against the target LED array requirements to ensure adequate drive capability without exceeding thermal limits.

LED Driver IC Part Context

The LT3950 belongs to Analog Devices' family of LED lighting driver ICs. It is distinct from synchronous buck drivers like the LT3964-1 or boost controllers like the MAX25560. The JMSE variant specifies the package type and pin configuration. The TRPBF suffix denotes the reel packaging format for automated assembly processes.

LED Driver IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Analog Devices LED drivers such as the LT3954 or LT8374 only if topology and current requirements align, but verify pin compatibility and electrical parameters independently.
