Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before finalizing procurement plans. Confirm that the SOIC-16 package and reel packaging align with assembly requirements. Ensure compatibility with the specified 9 V to 30 V input range and 50 kHz switching frequency for the target application design.
Selection Notes
Select this IC for offline two-stage LED driving applications requiring flyback topology. It is suitable for designs needing analog dimming and a single output channel. Consider the -20°C to +85°C operating temperature range and SOIC-16 package constraints when evaluating thermal management and board space limitations for large TV implementations.
Part Context
This component belongs to Monolithic Power Systems' LED lighting driver series, specifically targeting the offline two-stage market segment. It complements other MPS solutions like the MP4651 by offering distinct architectural features for larger display applications. The part is categorized under power management ICs focused on specialized illumination control.
Replacement Considerations
Public documentation indicates the MP4653 as a recommended replacement for new designs. Verify functional equivalence and pinout compatibility before substitution due to the NRND status of the MP4652ES-LF-Z.
