STMicroelectronics STEVAL-L7983ADJ Evaluation Boards

STMicroelectronics STEVAL-L7983ADJ Evaluation Boards are 0.3A step-down DC/DC converter based on the L7983PUR regulator with 12V set output voltage. These boards feature dynamic low consumption mode to low noise mode selection and internal soft-start. The soft start time is internally fixed and the output voltage supervisor manages the reset phase for any digital load (MCU and FPGA). The STEVAL-L7983ADJ evaluation boards offer an internal compensation network that features high noise immunity, simple design, and component cost savings. The RST open collector output can also implement output voltage sequencing during the power-up phase. The STEVAL-L7983ADJ evaluation boards are RoHS compliant and are ideally used in buck converters.
