STMicroelectronics 38V 5 W Synchronous Iso-Buck Converter Evaluation Board with Dual Isolated Output Based On The A6986I

The STMicroelectronics STEVAL-A6986IV1 evaluation board is based on ST A6986I automotive 38 V, 5 W synchronous iso-buck converter for isolated applications. The primary output voltage can be accurately adjusted, whereas the isolated secondary output is generated by a transformer. No optocoupler is required. The primary sink capability (typ. 1.9 A) allows a proper energy transfer to the secondary side and enables a tracked soft-start of the secondary output.

• Embedded primary output voltage supervisor
• Adjustable soft-start time
• Internal primary current limiting
• Overvoltage protection
