LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the package type matches the required 16-MSOP-EP footprint for PCB layout compatibility. Check RoHS compliance status if restricted substances are a constraint for the target application.

LED Driver IC Selection Notes

Select this component for applications requiring high input and output voltage ranges up to 100 V. It is suitable for designs needing external MOSFET control via its internal 7.15 V supply. Consider the thermal performance of the MSOP-EP package for heat dissipation requirements. Verify that the desired switching frequency falls within the 100 kHz to 1 MHz operational range.

LED Driver IC Part Context

This part belongs to the LT3756 series of high-voltage LED controllers. Variants such as LT3756EMSE-1 and LT3756EMSE-2 exist, often associated with specific reference designs or efficiency optimizations. The series is designed for driving high-current LEDs using external power switches controlled by the IC.

LED Driver IC Replacement Considerations

LT3756EMSE-2#TRPBF is a variant within the same family. LT3758EMSE#TRPBF offers similar high-voltage control but differs in pin count (MSOP-10) and specific topology support.
