TPSM63603: Vout = 12V – CISPR 32 class B emissions

Prodigy 215 points

Part Number: TPSM63603
Other Parts Discussed in Thread: TPSM63606EVM

Hi there,

I have some questions regarding the CISPR 32 class B emissions.

1. Do you have any EMC data for a 12V output (24V input)?

2. Is this also compliant with CISPR 32 class B emissions?

3. Also, what filter did you use or recommend?

Kind regards,

Hi LM,

We now have EMI test results for outputting 5V and 3.3V in the datasheet. I don't have the EMC data for the 12V output right now. But you can use our EVM to test the EMC under your working conditions. TPSM63603 meets CISPR 11 and 32 class B emissions within the scope of work given by the datasheet. You may need to add an input EMI filter to attenuate the conducted emission. The IC was designed to help minimize the radiated emission in the recommended layout pattern. For schematic, you can refer to our EVM user's guide. The links is shown below. Hope this can help you. Thanks.
