The ADuM50101 is an integrated, isolated dc-to-dc converter.
Table 1. Power Levels
Based on the Analog Devices, Inc., iCoupler® technology, the
Input Voltage (V) Output Voltage (V) Output Power (mW)
dc-to-dc converter provides regulated, isolated power, adjustable 5 5 150 between 3.15 V and 5.25 V. Input supply voltages can range 5 3.3 100 from slightly below the required output to significantly higher. 3.3 3.3 66 Popular combinations and their associated power levels are shown in Table 1. The iCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution. isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations. 1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329. Other patents are pending.
