STMicroelectronics STEVAL-A6986IV1 Iso-Buck Converter Eval Board
STMicroelectronics STEVAL-A6986IV1 Iso-Buck Converter Evaluation Board is configured to evaluate the operation of the A6986I automotive 38V, 5W synchronous iso-buck converter for isolated applications. The STEVAL-A6986IV1 Board's primary output voltage can be accurately adjusted, whereas a transformer generates the isolated secondary output. No optocoupler is required. The primary sink capability (Typ. 1.9A) allows a proper energy transfer to the secondary side and enables a tracked soft-start of the secondary output.
The STM STEVAL-A6986IV1 Iso-Buck Converter Evaluation Board generates two isolated voltages (positive around 18V and negative between 4V and 5V), especially suitable for supplying IGBT/SiC MOSFET gate driver. A simple bypass enables the supply of a single isolated voltage.
