LED Driver IC Procurement Notes

Verify component authenticity through authorized distribution channels due to the obsolete status of this specific part number. Confirm that the 14-TDFN package dimensions and pinout match the design requirements before procurement. Check for RoHS compliance documentation as required by regional regulations. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage prior to assembly.

LED Driver IC Selection Notes

Select this component when designing circuits requiring independent regulation for multiple white LED strings from a single low-voltage source. Consider the 125mA current capability and the 14-pin TDFN footprint constraints during PCB layout. Evaluate thermal dissipation needs given the exposed pad configuration. Verify compatibility with the host microcontroller's single-wire interface for dimming control signals.

LED Driver IC Part Context

This part belongs to the MAX8630 family of LED drivers from Analog Devices/Maxim Integrated. It is specifically engineered for portable consumer electronics where space and power efficiency are critical. The Y suffix typically denotes a specific temperature grade or version within the product line, while ETD indicates the tape and reel packaging format for automated assembly.

LED Driver IC Replacement Considerations
