CY39C604PNF-G-JNEFE1

Overview

The CY39C604PNF-G-JNEFE1 is an LED lighting driver IC manufactured by Infineon Technologies. It utilizes a flyback topology and operates as a primary side regulation (PSR) device. The component supports a single output channel with a maximum power dissipation of 800 mW. It functions within an input voltage range of 9 V to 20 V and maintains a supply current maximum of 5.6 mA. The operating frequency spans from 30 kHz to 133 kHz. The device is housed in an SOP-8 package and is rated for an extended temperature range from -40°C to +125°C. This specific variant is designated as obsolete.

Feature Summary

• Implements primary side regulation for simplified circuit design
• Supports flyback converter topology for isolated LED driving
• Designed for high reliability applications including space-grade environments

Applications

• LED lighting systems requiring SEU immunity
• Space-grade electronic equipment
• Industrial LED drivers operating in extended temperature ranges

Procurement Notes

This component is officially classified as obsolete or no longer manufactured by the producer. Availability is restricted to existing stock or surplus channels, which may involve significant lead times and price volatility. Verification of authenticity and lot traceability is critical due to the discontinued status. Buyers should confirm the specific suffix JNEFE1 matches their design requirements, as functional differences may exist between packaging variants. Regulatory compliance documentation should be reviewed prior to integration into new production lines.

Selection Notes

Engineers selecting this part must account for its obsolete status when designing long-term products. The SOP-8 package and PSR architecture are suitable for cost-sensitive, low-power LED applications. Designers should verify that the 9V to 20V input range aligns with their system's power supply constraints. Given the specialized nature of the JNEFE1 suffix, alternative components with similar flyback and PSR characteristics should be evaluated if future supply continuity is a priority.
