Overview
The SSL5237BTE/1Y is an AC-DC offline switcher designed for LED lighting applications. It utilizes a step-down (buck) topology to regulate output current. The device supports triac dimming functionality and delivers an output current of 800mA per channel. It operates within a voltage supply range of 9.9V to 16V. The component is housed in an 8-HSOIC package with dimensions of 0.154 inches (3.90mm) width and includes an exposed pad for thermal management.
Feature Summary
- Integrates a step-down converter topology for efficient LED drive control
- Supports triac dimming for compatibility with standard household switches
- Provides regulated constant current output for LED string stability
Applications
- Triac-dimmable LED lamps
- Offline LED lighting drivers
- General illumination fixtures requiring high power factor
Procurement Notes
Verify the specific suffix 'B' against the original design requirements, as it may indicate a specific binning or revision level compared to the base SSL5237 model. Confirm that the 8-HSOIC package footprint matches the PCB layout constraints. Ensure the 800mA output current rating aligns with the target LED load specifications. Check for any environmental compliance documentation required for the final assembly process.
Selection Notes
Select this component when a single-stage offline solution with integrated dimming is required. The 800mA current capability suits medium-power LED strings. The exposed pad design necessitates adequate copper area on the PCB for heat dissipation. Verify input voltage conditions fall within the specified operational range to ensure stable performance without external over-voltage protection circuits.
Part Context
This part belongs to NXP's SSL5237 family of LED drivers. It shares functional similarities with other members like the SSL5237TE/1Y but may differ in specific electrical characteristics or packaging revisions. The family targets cost-effective, high-performance lighting solutions. Understanding the broader family context helps in identifying compatible reference designs and evaluation boards for development purposes.
Replacement Considerations
The SSL5237TE/1Y is a related variant within the same product family. Verify if the 'B' suffix denotes a necessary upgrade or specific manufacturing lot requirement before substituting. Ensure pinout compatibility remains identical between the TE and B variants to avoid PCB redesign.
