Proven-technology quad digital isolator integrates isolated DC-DC converter

Available now from Mouser, Silicon Labs' Si88x4x quad digital isolators integrate proven technology with an on-chip isolated DC-DC converter. This provides regulated output voltages of 3.3 or 5.0V (or >5V with external components) at peak output power levels of up to 2W. The devices provide up to four digital channels. The DC-DC converter has a user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shut-down option and loop compensation. The ultra-low-power digital isolation channels offer substantial data-rate, propagation delay, size and reliability advantages over legacy isolation technologies. Data rates up to 100Mbps are supported, and all devices achieve propagation delays of only 23ns. Applications include industrial automation systems, electric vehicles, isolated power supplies, inverters, data acquisition, motor control, PLCs and distributed control systems.
