Applications
Differential and Common Mode filtering for DC-DC
converters with 48 V and 24 V input:
• Telecommunications
• Data communications
• Distributed Power Solutions
Description
The F4804 Input Filter minimizes the conducted and radiated emissions generated by switch mode DC-DC
converters, and allows board designs utilizing
emissions requirements.
Using the F4804 filter as the primary power-conditioning device in front of any of the
provide a “worry-free” EMI design. 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.
F4804 filter is designed specifically for distributed power solutions in conjunction with
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.
