STMicroelectronics STEVAL-L6983IV1 Synchronous Iso-Buck Eval Board
STMicroelectronics STEVAL-L6983IV1 Evaluation Board designed to evaluate L6983I, 38V, 10W synchronous iso-buck converter for isolated applications. This eval board features primary output voltage that can be accurately adjusted and isolated secondary output, which is derived by a given transformer ratio. The STEVAL-L6983IV1 eval board generates an isolated unregulated voltage and provides the possibility to use a post-regulation to generate a dual voltage.
