Overview
The CPC9909NE is an offline high-brightness LED driver manufactured by Littelfuse using a high-voltage BCDMOS on SOI process. It supports boost and buck topologies with an input voltage range of 8 V to 550 V. The device operates at switching frequencies between 30 kHz and 120 kHz, featuring adjustable output voltage and PWM dimming capabilities. Packaged in an SOIC-EP-Wide-8 format, it handles up to 2.5 W power dissipation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Supports both boost and buck converter topologies for flexible LED drive configurations
- Integrates PWM dimming functionality for precise brightness control
- Utilizes high-voltage BCDMOS on SOI technology for high efficiency
Applications
- Flat-panel display RGB backlighting
- Signage illumination systems
- Decorative lighting applications
Procurement Notes
Verify component authenticity through authorized Littelfuse distributors or certified partners. Confirm the specific suffix 'NE' matches the required wide-body SOIC package variant. Check current lifecycle status as end-of-life information may affect long-term availability. Ensure RoHS compliance documentation aligns with regional regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component for designs requiring high-efficiency offline LED driving with integrated dimming. The wide input voltage range accommodates various mains-powered applications. Consider thermal management due to the 2.5 W power dissipation rating. Verify that the single-channel output meets the target LED string configuration requirements without additional parallel drivers.
Part Context
Part of the CPC9909 series from Littelfuse, designed for cost-effective high-brightness LED solutions. Manufactured under the IXYS Integrated Circuits Division heritage, leveraging specialized high-voltage semiconductor processes. The series targets general illumination and display markets where efficiency and compact design are prioritized over complex multi-channel control.
Replacement Considerations
Check for CPC9909NETR if tape-and-reel packaging is required instead of tube. Evaluate alternative Littelfuse LED drivers if the CPC9909NE is discontinued. Ensure substitute parts maintain compatible input voltage ranges and switching frequency specifications.
