Procurement Notes
Verify the specific suffix NOPB confirms lead-free compliance and RoHS status against the latest manufacturer datasheet. Confirm the SOIC-8 package type matches your PCB footprint requirements. Ensure the analog dimming interface aligns with your control circuitry specifications before finalizing procurement.
Selection Notes
Select this component for designs requiring a single-channel LED driver with analog dimming capabilities. The SOIC-8 package suits surface-mount assembly processes. Verify that the input voltage range of 8 V to 13 V meets your system's power supply constraints and that the thermal management strategy accommodates the device's operating temperature limits.
Part Context
This part belongs to the LM3444 series of LED lighting driver ICs manufactured by Texas Instruments. It is categorized under LED Lighting Drivers and falls within the broader Power Management ICs (PMIC) family. The device is designed specifically for driving LEDs from AC mains sources using offline topologies.
Replacement Considerations
Check for direct pin-to-pin replacements within the LM3444 family or other TI LED drivers with similar SOIC-8 packaging and analog dimming support. Verify electrical parameter compatibility, including supply voltage range and output current capabilities, before substituting.
