1 (reinforced insulation) Description The Si88xx integrates Silicon Labs’ 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 2 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.
The ultra-low-power digital isolation channels offer substantial data-rate, propagation delay, size and reliability a...
