STMicroelectronics STEVAL-L7983ADJ Evaluation Boards
STMicroelectronics STEVAL-L7983ADJ Evaluation Boards are 0.3A step-down DC/DC converters based on the L7983PUR regulator with a 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, a simple design, and component cost savings. The RST open collector output can also implement output voltage sequencing during the power-up phase. The STMicroelectronics STEVAL-L7983ADJ evaluation boards are RoHS compliant and are ideally used in buck converters.Features
