The NIRSP31E device is a triple-channel digital isolator with integrated isolated DC-DC converter. The isolated DC-DC converter provides stable output voltage and up to 400mW output power by closed-loop control and transformer on chip. The feedback PWM signal is sent to the primary side by a digital isolator based on Novosense capacity isolation technology. The high integrated solution can help simplify system design, save PCB area and improve reliability. The NIRSP31E device supports 3kVrms insulation for 1min withstand voltage. The data rate of the NIRSP31E device is up to 20Mbps. The NIRSP31E device provides 5V to 5V, 5V to 3.3V, 3.3V to 3.3V conversion mode. The output voltage can be set by SEL pin.
