Description
The F4804 Input Filter minimizes the conducted and radiated emissions generated by switch mode dc-dc
converters, and allows board designs utilizing dc-dc converters to easily meet stringent Class B conducted
emissions requirements.
Unlike most available off-the-shelf filter modules, the F4804 contains, in addition to common mode noise reduction
components, a differential LC-filter stage, which guarantees compliance with conducted noise standards in the
whole frequency range from 150 kHz to 30 MHz, including fundamental switching frequency and its harmonics.
Test results show headroom of 15-20 dB for conducted noise quasi-peak levels, in relation to Class B
requirements; see Figs. 2-8.
The F4804 filter is designed specifically for distributed power solutions in conjunction with dc-dc converters. Low
profile and small size (only 0.75 sq. in.) in a surface mount package helps the system designer save real estate on
the system board, and simplifies the layout.
A single F4804 filter can be used with multiple converters, and is capable of providing up to a nominal 4 A to the
converter input bus. It can provide up to 3 A at 85 °C ambient with no airflow.
