Dual digital isolators with DC-DC converter integrate proven technology

Based on proven technology, Silicon Labs' Si88x2x dual digital Isolators with DC-DC converter are now available from Mouser stock. The devices provide regulated output voltages of 3.3V or 5V (or >5V with external components) at peak output power levels of up to 5W. They have up to two digital channels. The DC-DC converter has user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shutdown option and loop compensation. The device requires only minimal passive components and a miniature transformer. 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 max are supported, and all devices achieve propagation delays of only 23ns max. Applications include industrial automation systems, electric / hybrid electric vehicles, isolated power supplies, inverters, data acquisition, motor control, PLCs and distributed control systems.
