高稳定性隔离误差放大器 High Stability Isolated Error Amplifier
GENERAL DESCRIPTION
The ADuM31901 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 as compared to commonly used optocoupler and shunt regulator solutions.
