... Practical EMC results The EVB10801 is designed for a good electromagnetic emission behaviour. Please refer to the MLX10801 IC specification as well as to the available application notes for EMC considerations. The conducted electromagnetic emission measurement (according to IEC 61967-4) was performed using the following setup for the EVB10801: ...

... If good emission behaviour is not an issue (e.g. industrial/consumer applications), smaller caps (for C3/C4) as well as an unshielded coil can be used. Thus, size and cost can be reduced once more. 390121080102 Rev. 004 Author: SSZ Evaluation board EVB10801 Power LED driver for automotive applications For the latest version of this document our website at: www.melexis.com ...
