• Single-channel output configuration

Applications

• Offline white LED lighting systems
• General illumination drivers

Procurement Notes

Verify the current lifecycle status before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm that the SOIC-8 package and specific electrical parameters align with existing design requirements. Check for updated replacement recommendations from the manufacturer due to the end-of-life designation.

Selection Notes

Select this component only if the design accommodates the NRND status and requires an offline buck LED driver with 110 kHz switching. Ensure the input voltage fits the 8 V to 10.5 V range. Consider alternative active components if long-term availability is critical for new production runs.

Part Context
