ADUM3472ARSZ-RL7

ADUM3472ARSZ-RL7 is a quad-channel digital isolator with an integrated PWM controller and transformer driver for an isolated DC-to-DC converter. Based on the Analog Devices, Inc., iCoupler® technology, the DC-to-DC converter provides up to 2W of regulated, isolated power at 3.3V to 24V from a 5V input supply or from a 3.3V supply. This eliminates the need for a separate, isolated DC-to-DC converter in 2W isolated designs. It is approved by UL recognition: 2500V rms for 1 minute per UL 1577, CSA component acceptance notice #5A, VDE certificate of conformity, DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, VIORM = 560V peak. It is used in applications such as RS-232/RS-422/RS-485 transceivers, industrial field bus isolation, power supply start-up bias and gate drives, isolated sensor interfaces, process controls, and automotive.
