FAN7711N

Overview

The FAN7711N is a ballast controller IC from onsemi, designed for electronic ballast applications. It operates within a frequency range of 48.7kHz to 57.3kHz and requires a supply voltage between 12.4V and 15.2V. The device draws a typical supply current of 3.2 mA and functions reliably across an operating temperature range of -25°C to 125°C. It is housed in an 8-DIP package with a width of 0.300 inches (7.62mm). This component is classified as obsolete and is no longer manufactured by the supplier.

Feature Summary

• Integrated control logic for electronic ballast systems
• Fixed operating frequency range suitable for standard lighting applications
• Surface-mount or through-hole compatible packaging options available within the series

Applications

• Electronic ballast control circuits
• Fluorescent lamp power supplies
• Lighting system controllers

Procurement Notes

Verify part status carefully as this component is officially listed as obsolete and no longer manufactured. Confirm availability through secondary market distributors if sourcing is required. Ensure that any replacement components meet the original electrical specifications and pinout compatibility. Check for RoHS compliance documentation if environmental regulations apply to the end product. Validate lead times and authenticity when purchasing from non-authorized sources due to the discontinued status.

Selection Notes

Consider the FAN7711SMX or FAN7711MX variants if surface-mount technology is preferred over the through-hole DIP package offered by the N suffix. Evaluate the FAN7711M for similar performance characteristics in a smaller SOIC footprint. Ensure that the selected alternative supports the required 48.7kHz to 57.3kHz frequency range and 12.4V to 15.2V supply voltage constraints. Verify thermal management requirements against the -25°C to 125°C operating temperature specification.

Part Context

The FAN7711N belongs to the FAN7711 family of ballast controllers produced by onsemi. This series includes various package options such as SOP, SOIC, and DIP configurations to accommodate different PCB layout requirements. The N suffix specifically denotes the 8-DIP through-hole package variant. These devices are engineered for cost-effective and reliable operation in lighting applications requiring precise frequency control.

Replacement Considerations

The HT8822N is documented as a direct substitute for the FAN7711N. Verify pin compatibility and electrical parameters before implementation.
