SSL5236BTE/1Y

Overview

The SSL5236BTE/1Y is an integrated LED driver IC manufactured by NXP USA Inc., designed for off-line AC-DC switch-mode power supply applications. It utilizes a buck topology and features an internal switch, eliminating the need for external power components in many configurations. The device supports Triac dimming functionality, making it suitable for smart lighting systems requiring phase-cut compatibility. It provides a single output channel capable of driving up to 450mA. The component operates within a supply voltage range of 9.9V to 16V and is rated for junction temperatures between -40°C and 160°C. It is housed in an 8-HSO (HSOIC) package with a 3.90mm width.

Feature Summary

• Supports Triac dimming for compatibility with leading-edge and trailing-edge phase-cut dimmers
• Integrates an internal high-voltage switch for simplified circuit design
• Operates as an off-line AC-DC converter using a buck topology
• Capable of delivering up to 450mA output current for LED string regulation

Applications

• Off-line LED lighting fixtures
• Triac-dimmable general illumination lamps
• AC-DC LED drivers for residential and commercial use
• Smart lighting control modules

Procurement Notes

Verify availability status carefully, as this specific part number may be discontinued or subject to limited stock depending on the distributor. Confirm the exact suffix '1Y' matches your bill of materials, as variations exist within the SSL5236 family. Check RoHS compliance documentation for environmental regulations. Ensure the 8-HSO package dimensions align with your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when designing non-isolated AC-DC LED drivers requiring Triac dimming support. It is appropriate for applications needing a single-channel output up to 450mA without external switching transistors. Consider the wide operating temperature range (-40°C to 160°C TJ) for high-thermal environments. Verify input voltage ranges and ensure the buck topology fits the system's voltage step-down requirements.

Part Context

The SSL5236 belongs to NXP's SSL series of LED driver controllers, which are optimized for cost-effective and compact lighting solutions. This series typically integrates protection features and dimming interfaces common in modern solid-state lighting. The BTE variant indicates a specific thermal and packaging configuration within the broader SSL5236 product line, focusing on surface-mount assembly efficiency.

Replacement Considerations

Consult official NXP documentation for direct pin-to-pin replacements or updated generations within the SSL5236 family. Verify functional equivalence regarding dimming characteristics and maximum output current if substituting with other NXP LED driver ICs.
