The ADuM5000W1 is an isolated dc-to-dc converter based on isoPower uses high frequency switching elements to transfer power the Analog Devices, Inc., iCoupler® technology. The dc-to-dc through its transformer. Special care must be taken during printed converter in this device provides regulated, isolated power in circuit board (PCB) layout to meet emissions standards. See the several combinations of input and output voltages as listed in AN-0971 Application Note for board layout recommendations. Table 1.

transfers isolated power in this dc-to-dc converter with up to 5 5 400 33% efficiency. The result is a small form factor, total isolation 5 3.3 330 solution. 3.3 3.3 132 Higher output power levels are obtained by using the ADuM5000W to augment the power output of ADuM5401, ADuM5402, ADuM5403, ADuM5404, ADuM520x, and other ADuM5000W iCouplers with isoPower®. 1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.
