STMicroelectronics STEVAL-ISA209V1 Evaluation Board
STMicroelectronics STEVAL-ISA209V1 Evaluation Board is used to evaluate the L6983 synchronous monolithic step-down regulator. The regulator is capable of delivering up to 3A DC to the load. A wide input voltage range makes the device suitable for a broad range of applications. The STMicroelectronics L6983NQTR used in this evaluation board is based on peak current mode architecture and is packaged in a 3mm x 3mm QFN-16 package with internal compensation, thus minimizing design complexity and size.
