GENERAL DESCRIPTION
The ADuM50101 is an integrated, isolated dc-to-dc converter.
Based on the Analog Devices, Inc., iCoupler® technology, the
dc-to-dc converter provides regulated, isolated power, adjustable
between 3.15 V and 5.25 V. Input supply voltages can range
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.

ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
All typical specifications are at TA = 25°C, VDDP = VISO = 3.3 V, VSEL resistor network: R1 = 10 kΩ, R2 = 16.9 kΩ. Minimum/maximum
specifications apply over the entire recommended operation range which is 3.0 V ≤ VDDP, VSEL, VISO ≤ 3.6 V, and −40°C ≤ TA ≤ +105°C,
unless otherwise noted. Switching specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.
