Quad-channel digital isolator combines four isolated logic channels with an integrated PWM controller and transformer driver for isolated power conversion. The channel configuration provides three forward channels and one reverse channel. The device supports regulated isolated dc-to-dc converter designs with external transformer circuitry and up to 2 W output power. Logic operation supports 3 V to 5.5 V supplies, 25 Mbps data rate, and high common-mode transient immunity. Industrial operation is specified from -40 °C to 105 °C in 20-lead wide-body package options.
