Isolated 5-V bias supply for automotive CISPR 25: class 5 emissions: reference design
Description
This reference design demonstrates EMI mitigation techniques required for a high frequency: reinforced 5-kVRMS isolated: 5-V bias DC/DC converter module to pass the automotive: CIPSR 25: class 5: EMC test standard. The design features a 500-mW: high efficiency bias supply with integrated transformer: control and power stage in a 2.65 mm height SOIC-16 package solution. Typical bias examples include: digital isolators: voltage and current sensing: CAN transceivers and signal communication used in the design of traction inverters: on-board chargers: battery management systems: infotainment: charging cables and PTC heaters.
