- Programmable current LED applications
Procurement Notes
Verify the End-of-Life (EOL) status directly with Microchip Technology before procurement, as this component is listed as obsolete. Confirm availability through authorized distributors or factory special orders. Ensure design-in decisions account for potential supply constraints associated with discontinued parts.
Selection Notes
Select this component for single-channel buck converter LED designs requiring high input voltage tolerance up to 400 V. It is suitable for applications needing precise 50 mA current regulation and integrated PWM dimming. Consider the SOIC-8 package constraints and operating temperature limits when designing the thermal management system.
Part Context
This part belongs to the HV9925 family of LED drivers from Microchip Technology. These devices are designed for high-efficiency lighting solutions, specifically targeting applications where high input voltages and programmable current settings are required. The SG suffix indicates specific packaging and environmental compliance details.
Replacement Considerations
As the component is marked End-of-Life, direct substitutes may not be available. Evaluate alternative Microchip LED drivers with similar buck topologies and voltage ratings. Verify pin compatibility and electrical specifications against new candidates.
