LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the part number corresponds to the Analog Devices Inc. manufacturer designation. Ensure compatibility with the required 16-MSOP-EP footprint during procurement planning. Cross-reference the datasheet revision history for any recent package or material changes before finalizing orders.

LED Driver IC Selection Notes

Select this component for designs requiring wide input voltage ranges up to 60V and high output voltages up to 100V. Consider the integrated thermal derating feature if operating in environments with limited heat dissipation. Evaluate the need for PWM versus analog dimming based on system control requirements. Ensure external MOSFET selection aligns with the internal 7.15V gate drive capability.

LED Driver IC Part Context
