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. Table 1. The Analog Devices chip scale transformer, iCoupler technology, Input Voltage (V) Output Voltage (V) Output Power (mW) transfers isolated power in this dc-to-dc converter with up to 5 5 500 33% efficiency. The result is a small form factor, total isolation 5 3.3 330 solution. 3.3 3.3 200 Higher output power levels are obtained by using the ADuM5000 to augment the power output of ADuM5401, ADuM5402, ADuM5403, ADuM5404, ADuM520x, and other ADuM5000 iCouplers with isoPower. 1 Protected by U.S. Patents 5,952,849 6,873,065 6,903,578 and 7,075,329.
