ADUM3190WSRQZ-RL7 Description

The ADUM3190WSRQZ-RL7 is an isolated error amplifier based on Analog Devices, Inc., iCoupler® technology. The ADuM3190 is ideal for linear feedback power supplies. The primary side controllers of the ADuM3190 enable improvements in transient response, power density, and stability compared to commonly used optocoupler and shunt regulator solutions. Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over a lifetime and at high temperatures, the ADUM3190WSRQZ-RL7 transfer function does not change over its lifetime and is stable over a wide temperature range of −40°C to +125°C.
