FL5150MX

Power Management - Specialized Overview

The FL5150MX is an integrated controller designed for IGBT and MOSFET AC phase cut dimmer applications. It operates within a wide supply voltage range of 90VAC to 305VAC, supporting high-voltage offline environments. The device features three independent output channels with specific current ratings of 53.6mA, 93.8mA, and 104.2mA per channel. It supports analog, PWM, and TRIAC dimming methods. The component functions reliably across a junction temperature range of -40°C to +125°C and is housed in an 8-SOIC package with an exposed pad.

• Offline power supplies for lighting control modules

Power Management - Specialized Procurement Notes

Verify the exact ordering suffix against the official onsemi datasheet to ensure correct packaging and temperature grade specifications. Confirm that the FL5150MX designation aligns with current Fairchild Semiconductor integration updates, as underscore characters may have been replaced by dashes in recent part number nomenclature changes. Cross-reference the package marking and pinout diagrams with the latest documentation to prevent integration errors during PCB design and assembly processes.

Power Management - Specialized Selection Notes

Select this component when designing AC phase-cut dimmers that require direct drive capability for IGBT or MOSFET switches. The three-channel output structure allows for differentiated current sourcing suitable for various gate drive requirements. Ensure the application environment stays within the specified -40°C to +125°C junction temperature limits. Verify compatibility with the intended dimming protocol, whether analog, PWM, or TRIAC-based, to match system control architecture needs.

Power Management - Specialized Part Context

The FL5150MX belongs to the broader portfolio of power management and lighting control solutions offered by onsemi. Following the integration of Fairchild Semiconductor, many legacy part numbers underwent nomenclature adjustments, particularly regarding character replacements in the naming convention. This controller addresses the growing demand for efficient, high-voltage offline lighting control ICs that simplify the design of robust AC dimming systems.

Power Management - Specialized Replacement Considerations

Consult the official onsemi replacement matrix for verified cross-references. Note that legacy Fairchild part numbers containing underscores may require conversion to dash-separated formats in new orders. Do not assume functional equivalence with similar model numbers without verifying electrical parameters and pin configurations against current datasheets.
