ADUM4190SRIZ, Разделительный усилитель, 1 Усилитель, 5 kVrms, 3В до 20В, WSOIC, 16 вывод(-ов)

ADUM4190 is an isolated error amplifier based on Analog Devices, Inc., iCoupler® technology. The device is ideal for linear feedback power supplies. The primary side controllers of the device enable improvements in transient response, power density, and stability as compared to commonly used optocoupler and shunt regulator solutions. Included in the device is a wideband operational amplifier for a variety of commonly used power supply loop compensation techniques. The device is fast enough to allow a feedback loop to react to fast transient conditions and overcurrent conditions. Also included is a high accuracy 1.225V reference to compare with the supply output setpoint. It is widely used in application such as linear feedback power supplies, inverters, uninterruptible power supplies (UPS) DOSA-compatible modules, voltage monitors etc.
