APPLICATIONS Power supply start-up bias and gate drives Isolated sensor interfaces Industrial PLCs GENERAL DESCRIPTION 1 Table 1. Power Levels The ADuM5010 is an integrated, isolated dc-to-dc converter. Input Voltage (V) Output Voltage (V) Output Power (mW) Based on the Analog Devices, Inc., iCoupler technology, the 5 5 150 dc-to-dc converter provides regulated, isolated power, adjustable 5 3.3 100 between 3.15 V and 5.25 V. Input supply voltages can range 3.3 3.3 66 from slightly below the required output to significantly higher. 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. Rev.
