This provides manufacturers of ac-to-dc and dc-to-dc power supplies, including those that are DOSA-compliant, with a significant upgrade in speed and operating temperature range, as well as a 5× improvement in transient response.
Designed with ADI’s iCoupler? digital isolation technology, the ADUM3190
eliminate the CTR of optocouplers that degrades over the lifetime of the devices and limits operation to 85˚C. The ADuM3190 and ADuM4190 include a highly accurate 1.225-V reference and a wideband operational amplifier that can be used to set up a variety of commonly used power supply loop compensation techniques.
