Low-cost three-channel digital isolator with integrated isolated power DC-DC converter

NIRSP31V is triple-channel digital isolators 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 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. NIRSP31V supports 3kVrms insulation 1min withstand voltage. The data rate of the NIRSP31  is up to 20Mbps, and the common-mode transient immunity (CMTI) is up to ±50kV/us. The NIRSP31V provide 5V to 5V, 5V to 3.3V, 3.3V to 3.3V conversion mode. The output voltage can be set by SEL pin.
