GENERAL DESCRIPTION
The ADuM5401W/ADuM5402W/ADuM5403W1 devices are
quad-channel digital isolators with isoPower®, an integrated,
isolated dc-to-dc converter. Based on the Analog Devices, Inc.,
iCoupler® technology, the dc-to-dc converter provides up to
500 mW of regulated, isolated power at 5.0 V (see Table 1).
These devices eliminate the need for a separate, isolated dc-to-
dc converter in low power, isolated designs. The iCoupler chip
scale transformer technology is used to isolate the logic signals
and for the magnetic components of the dc-to-dc converter.
The result is a small form factor, total isolation solution.
The ADuM5401W-1/ADuM5402W-1/ADuM5403W-1
versions of the isolators provide an upgraded voltage reference
to ensure proper startup under all load conditions (see the
Ordering Guide for more information).
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
Typical specifications are at TA = 25°C, VDD1 = VISO = 3.3 V, VSEL = GNDISO. Minimum/maximum specifications apply over the entire
recommended operation range, which is 3.0 V ≤ VDD1, 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.

barrier.

1 All voltages are relative to their respective grounds.
2 VISO provides current for dc and dynamic loads on the VISO I/O channels. This
current must be included when determining the total VISO supply current. For
ambient temperatures from 85°C to 105°C, the maximum allowed current is
reduced.
3 VDDI and VDDO refer to the supply voltages on the input and output sides of a
given channel, respectively. See the PCB Layout section.
4 See Figure 5 for the maximum rated current values for various temperatures.
5 Refers to common-mode transients across the insulation barrier. Common-
mode transients exceeding the absolute maximum ratings may cause latch-up
or permanent damage.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
