FAN7711ZMX

Overview

The FAN7711ZMX is a ballast control integrated circuit designed for high-performance fluorescent lamp electronic ballasts. It operates within a frequency range of 48.7kHz to 57.3kHz and supports a supply voltage of 12.4V to 15.2V. The device functions in an operating temperature range of -25°C to 125°C and utilizes an 8-SOIC surface-mount package.

Feature Summary

• Integrates adaptive zero-voltage switching (ZVS) control circuitry for efficient operation
• Includes internal oscillators, dead-time control, and preheat timing circuits
• Features low start-up current and active charge pump for bootstrap driver operation

Applications

• Electronic ballast design for fluorescent lamps
• High-efficiency lighting systems requiring ZVS topology

Procurement Notes

Verify the specific suffix 'ZMX' against official onsemi documentation, as standard listings typically reference 'FAN7711MX'. Confirm component status, noting that the base FAN7711 series has received End-of-Life notifications. Ensure the package width matches the specified 8-SOIC dimensions during integration.

Selection Notes

Select this component for designs requiring integrated ZVS and preheat functionality without external logic. Verify compatibility with the LCC resonant tank circuit parameters. Check if the 8-pin SOIC footprint meets PCB layout constraints compared to DIP alternatives.

Part Context

This part belongs to the FAN7711 family of ballast controllers originally developed by Fairchild Semiconductor and later acquired by onsemi. The series provides a complete solution for resonant inverters, combining control logic with gate drivers to simplify ballast architecture.
