Overview
The SSL5237TE/1Y is a dimmable LED driver IC designed for AC-DC offline switching applications. It integrates a triac dimming interface and supports both step-down (buck) and step-up (boost) converter topologies. The device delivers an output current of 800mA and operates with a mains voltage rating of 700V. It features a built-in 10 Ohm switch resistance. Packaged in an 8-HSO format, this component provides brightness control capabilities suitable for general lighting applications requiring high power factor performance.
Feature Summary
- Integrates triac dimming capability for compatibility with standard household dimmers
- Supports flexible buck and boost converter topologies for various LED configurations
- Provides integrated brightness control functions within a compact package
Applications
- AC-DC offline switching LED lighting systems
- Triac-dimmable general illumination fixtures
- Buck or boost topology LED drivers
Procurement Notes
Verify the discontinued status with authorized distributors before procurement planning. Confirm that the 8-HSO package matches your PCB footprint requirements. Ensure the 800mA output current specification aligns with your LED array design. Check for RoHS compliance documentation if required by your manufacturing standards. Validate availability through official NXP channels as stock may be limited.
Selection Notes
Select this component when designing dimmable LED drivers requiring integrated triac detection. The 800mA current rating suits medium-power LED arrays. Consider the 700V mains rating for direct line connection designs. The dual buck/boost capability allows flexibility in input voltage ranges relative to LED forward voltage. Ensure thermal management accounts for the integrated switch characteristics.
Part Context
This part belongs to NXP's SSL series of LED lighting drivers. It is categorized under analog and mixed-signal components specifically for LED illumination. The device addresses the need for cost-effective, high-performance dimming solutions in residential and commercial lighting markets.
Replacement Considerations
