Design considerations
- Provide high power input to 12 V with Hot swap functionality
- Avoid potential noise coupling signal integrity issue, which can be introduced by the 48 V rail running on motherboards
- For board level reliability and best performance we recommend LFPAK56 and LFPAK88 devices
- Better Rdson and body diode behaviour is important for efficiency and for conducted and radiated emissions
- Provide adequate ESD protection to minimize potential of damage from transient voltages
