FAN7711SMX

Overview

The FAN7711SMX is a ballast controller manufactured by onsemi, operating within a frequency range of 48.7kHz to 57.3kHz. It functions with a supply voltage between 12.4V and 15.2V and draws a supply current of 3.2 mA. The device is housed in an 8-SOIC package (0.154" width) and supports surface mount mounting. It operates across a temperature range of -25°C to 125°C. This component is currently classified as obsolete.

Feature Summary

• Integrated control for cold cathode fluorescent lamp (CCFL) ballast applications
• Designed for operation at fixed frequencies around 57.3 kHz
• Supports surface mount packaging for automated assembly

Applications

• Cold Cathode Fluorescent Lamp (CCFL) backlighting systems
• LCD monitor and television backlight inverters
• General purpose CCFL ballast circuits

Procurement Notes

Verify the obsolete status of this part number before integration into new designs. Confirm that existing inventory or surplus sources meet quality standards. Check for RoHS compliance documentation if required for specific regional regulations. Ensure the 8-SOIC package dimensions align with the target PCB footprint. Validate that the operating temperature range suits the final application environment.

Selection Notes

Select this component only for maintenance or replacement of existing CCFL-based designs. Evaluate alternative active controllers if designing new equipment due to obsolescence. Consider the fixed frequency operation when matching transformer specifications. Verify supply voltage requirements against available power rails. Assess thermal management needs given the wide operating temperature range.
