LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix matches project requirements, as packaging variations exist between tube and tape-and-reel formats. Ensure supply chain stability due to potential limited availability status reported by major retailers. Validate RoHS compliance documentation prior to integration into final assemblies.

LED Driver IC Selection Notes

Select this controller when high input voltage tolerance up to 110 V is required for LED applications. Consider the wide operating temperature range for harsh environments. Evaluate the need for single-channel constant-current regulation versus multi-channel solutions. Assess compatibility with external MOSFETs and inductors for the chosen topology. Verify that the TSSOP-28 package fits the PCB layout constraints.

LED Driver IC Part Context

This part belongs to the LT3795 series of LED controllers manufactured by Analog Devices. It is specifically engineered to regulate constant-current or constant-voltage outputs for driving LEDs efficiently. The device integrates low-side external switch driving capabilities to reduce electromagnetic interference (EMI) compared to high-side driving solutions.

LED Driver IC Replacement Considerations
