Lighting, Ballast Controllers Procurement Notes

Verify the specific datasheet version from Infineon Technologies to confirm pinout compatibility and electrical characteristics. Ensure the 20-SOIC package dimensions match your PCB layout requirements. Cross-reference the supply voltage range of 10.4V to 16.5V with your power stage design. Confirm that the 41kHz to 47kHz operating frequency aligns with your transformer specifications.

Lighting, Ballast Controllers Selection Notes

Select this component when a combined PFC and ballast solution is required for fluorescent lamps. The integrated half-bridge driver reduces external component count. Verify that the operating frequency range suits your magnetic components. Ensure the supply voltage range matches your auxiliary power supply capabilities. Consider the thermal performance of the 20-SOIC package for your enclosure design.
