Always follow TI’s setup and application instructions, including use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure your personal safety and those working around you. Contact TI's Product Information Center http://support/ti./com for further information.
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions may result in personal injury, property damage or death due to electrical shock and burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed circuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified professional users having training, expertise and knowledge of electrical safety risks in development and application of high voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas Instruments. If you are not suitable qualified, you should immediately stop from further use of the HV EVM.
While the EVM is energized, never touch the EVM or its electrical circuits, as they could be at high voltages capable of causing electrical shock hazard.
Limitation for safe use:
EVMs are not to be used as all or part of a production unit.
The UCC28C56EVM-066 is a highly efficient primary-side controlled (using an AUX winding) flyback auxiliary power supply for EV/HEV automotive power trains. The design provides 15.2-VTYP, 40-W output for 800-V battery systems. It will deliver 40 W over the input voltage range from 125 V to 1000 V. The exact output voltage is load dependent. From 40-V to 125-V input the design will supply 20 W. The EVM utilizes a 1700-V silicon-carbide (SiC) MOSFET, making it ideal for 800-V battery systems.
The EVM is a 4-layer board with the top and bottom layers dedicated to signal and power routing. The two inner layers are used only to route test points. In effect, this is a low-cost two-layer PCB. The controller and it's associated power components are tightly compacted into a 50 mm x 86 mm area, highlighted by the white rectangle show on the top silkscreen. Note, C1 is not included with the critical components because it's considered to be part of the general VIN bypass capacitors in the system.
Every effort was made to use automotive qualified components. An automotive qualified 1700-V SiC MOSFET is listed in the BOM. The flyback transformer should be automotive qualified with consultation from the given transformer manufacturer.
