ISOW7741中文资料具有集成电源的低辐射、低纹波、四通道、3/1、增强型数字隔离器数据手册TI规格书

描述 Description

The ISOW7741 device is a galvanically-isolated quad-channel digital isolator with an integrated high-efficiency power converter with low emissions. The integrated DC-DC converter provides up to 550 mW of isolated power, eliminating the need for a separate isolated power supply in space-constrained isolated designs.
