Quad Digital Isolators with DC-DC Converter
The Si88xx integrates Skyworks’ proven digital isolator technology with an on-chip isolated dc-dc converter that provides regulated output voltages of 3.3 or 5.0 V (or >5 V with external components) at peak output power levels of up to 5 W. These devices provide up to four digital channels. The dc-dc converter has user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shut-down option and loop compensation. The device requires only minimal passive components and a miniature transformer.
