Medical equipment illumination

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 exactly, as variations exist without the suffix or with different package types. Check current availability status as supply may be limited.

LED Driver IC Selection Notes

Select this component when dual-channel constant current regulation is required. The 2MHz frequency allows for smaller inductors compared to lower frequency alternatives. Ensure the application requires I2C digital control for dimming adjustments. Verify that the 1.6A per channel output current meets the load requirements.

LED Driver IC Part Context

This part belongs to the LT3964 family of LED drivers from Analog Devices. It is distinct from the LT3958, which is a high-voltage boost/flyback converter, and the LT3956, which is a single-channel driver. The LT3964 specifically addresses multi-string LED applications requiring synchronized buck conversion.
