FLS2100A

Overview

The FLS2100A is a half-bridge LLC resonant control IC designed for LED lighting applications. It integrates a high-voltage MOSFET and controller to support boost and buck topologies. The device operates with an input voltage of 12.5 V and delivers an output current of 10.5 A. It functions at a working frequency of 300 kHz with adjustable output voltage. The component is housed in a SIP-9 package, supports through-hole mounting, and includes short circuit and thermal protection features.

Feature Summary

Integrates half-bridge LLC resonant control with high-voltage MOSFET
Supports boost and buck converter topologies for LED drivers
Includes integrated short circuit and thermal protection mechanisms

Applications

General LED lighting systems
LED illumination driver circuits

Procurement Notes

Verify the specific suffix (e.g., XS) as it may indicate packaging or revision differences. Confirm lifecycle status, as some listings indicate end-of-life or obsolescence. Ensure compatibility with existing PCB footprints for SIP-9 packages. Check RoHS compliance details against current regulatory requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring integrated half-bridge LLC control. Verify that the 12.5 V input range matches the system power supply. Ensure the 10.5 A output current capability meets load requirements. Consider the SIP-9 package constraints for thermal management and board layout during the design phase.

Part Context

This part belongs to the UniFET series by onsemi (formerly Fairchild Semiconductor). It is classified under LED Lighting Drivers and Driver ICs. The technology combines power switching and control logic into a single package to simplify LED driver design and reduce component count.
