STMicroelectronics STEVAL-ISA189V1 Evaluation Board
STMicroelectronics STEVAL-ISA189V1 Evaluation Board is based on the A6986F5V, which can deliver up to 1.5A and withstand cold crank events and wide input operating voltage ranges. The STEVAL-ISA189V1 is AEC Q100-qualified and is the ideal choice for battery-powered automotive systems. The board has synchronous rectification for higher efficiency at full load and application compactness. High-frequency switching (programmable up to 2MHz) helps to reduce size and cost of power passive components while remaining outside the AM band.
