Part Number: TPSF12C1

Tool/software:

Hi all,

I have two questions about how to use the TPSF12C1.

1) The recommended circuit always uses 2CM coils, Is it needed 2coils?

2) This IC is listed as compatible with IEC61000-4-5. Why is it compatible? Please provide more details.

Please let me know if you have an application note with details.

Best Regards,

Ryusuke

Hello Fukunaga,

Yes, the architecture is based for a two-stage filter. two CM choke coils are needed.

Yes, the device has inherent protection features for robust design – Withstands surge of 6 kV (IEC 61000-4-5) with minimal external component count. Please refer to datasheet page 19 and 20 for more details. TPSF12C1 Standalone, Active, EMI Filter for Common-mode Noise Mitigation in Single-Phase, AC, Power Systems datasheet (Rev. A)

Also, the following application note can help you with more information on the architecture - How Active EMI Power-Supply Filter ICs Mitigate Common-Mode Emissions
