STMicroelectronics STEVAL-ISA190V1 Evaluation Board

STMicroelectronics STEVAL-ISA190V1 Evaluation Board is based on the A6986F synchronous step-down switching regulator. The default evaluation board settings are 6V output voltage configured in LCM, 500kHz switching frequency, high-level ISKIP current, and the switchover feature disabled. These configurations can be changed to evaluate different application scenarios.
