3 Description

The ISOW7821 device is a high-performance, dualchannel

reinforced digital isolators with an integrated

high-efficiency power converter. The integrated DCDC

converter provides up to 650 mW of isolated

power at high efficiency and can be configured for

various input and output voltage configurations.

Therefore this device eliminates the need for a

separate isolated power supply in space-constrained

isolated designs.
