GENERAL DESCRIPTION
The ADuM60101 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 combination 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.

APPLICATIONS INFORMATION
the power effectively as well as to set the output voltage and
The dc-to-dc converter section of the ADuM6010 works on
principles that are common to most modern power supplies.
It has split controller architecture with isolated pulse-width
modulation (PWM) feedback. VDDP power is supplied to an
oscillating circuit that switches current into a chip-scale air core
transformer. Power transferred to the secondary side is rectified
and regulated to a value between 3.15 V and 5.25 V depending
on the setpoint supplied by an external voltage divider (see
Equation 1). The secondary (VISO) side controller regulates
the output by creating a PWM control signal that is sent to the
primary (VDDP) side by a dedicated iCoupler data channel. The
PWM modulates the oscillator circuit to control the power being
sent to the secondary side. Feedback allows for significantly higher
power and efficiency.

The power supply section of the ADuM6010 uses a 125 MHz
oscillator frequency to efficiently pass power through its chip-
scale transformers. Bypass capacitors must do more than one
job and must be chosen carefully. Noise suppression requires a
low inductance, high frequency capacitor; ripple suppression
and proper regulation require a large value bulk capacitor.
These capacitors are most conveniently connected between

.
Because the output voltage can be adjusted continuously
there are an infinite number of operating conditions. This
data sheet addresses three discrete operating conditions in the
Specifications tables. Many other combinations of input and
output voltage are possible; Figure 13 depicts the supported
voltage combinations at room temperature. Figure 13 was
generated by fixing the VISO load and decreasing the input
voltage until the PWM was at 80% duty cycle. Each of the
curves represents the minimum input voltage that is required
for operation under this criterion. For example, if the applica-
tion requires 30 mA of output current at 5 V, the minimum
input voltage at VDDP is 4.25 V. Figure 13 also illustrates why
the VDDP = 3.3 V input and VISO = 5 V configuration is not
recommended. Even at 10 mA of output current, the PWM
cannot maintain less than 80% duty factor, leaving no margin
to support load or temperature variations.

.
To suppress noise and reduce ripple, a parallel combination of at
least two capacitors is required. The recommended capacitor
values are 0.1 µF and 10 µF for VDD1. The smaller capacitor
must have a low ESR; for example, use of an NPO or X5R ceramic
capacitor is advised. Ceramic capacitors are also recommended for
the 10 mF bulk capacitance. An additional 10 nF capacitor can be
added in parallel if further EMI/EMC control is desired.
Note that the total lead length between the ends of the low ESR
capacitor and the input power supply pin must not exceed 2 mm.

Typically, the ADuM6010 dissipates about 17% more power
between room temperature and maximum temperature; there-
fore, the 20% PWM margin covers temperature variations.
ADuM6010
The ADuM6010 implements undervoltage lockout (UVLO)
with hysteresis on the primary and secondary sides I/O pins
as well as the VDDP power input. This feature ensures that the
converter does not go into oscillation due to noisy input power
or slow power-on ramp rates.

PCB LAYOUT
In applications involving high common-mode transients, design
the board layout such that any coupling that does occur equally
affects all pins on a given component side. Failure to ensure this can
cause voltage differentials between pins, exceeding the absolute
maximum ratings specified in Table 13, and thereby leading to
latch-up and/or permanent damage.
The ADuM6010 digital isolator, with a 0.15 W isoPower integrated
dc-to-dc converter, requires no external interface circuitry
for the logic interfaces. Power supply bypassing with a low ESR
capacitor is required as close to the chip pads as possible. The
isoPower inputs require several passive components to bypass

working voltage approved by agency testing is higher than the
50-year service life voltage. Operation at working voltages
higher than the service life voltage listed leads to premature
insulation failure.
The insulation lifetime of the ADuM6010 depends on the voltage
waveform type imposed across the isolation barrier. The iCoupler
insulation structure degrades at different rates, depending on
whether the waveform is bipolar ac, unipolar ac, or dc. Figure 19,
Figure 20, and Figure 21 illustrate these different isolation voltage
waveforms.
THERMAL ANALYSIS
The ADuM6010 consist of two internal die attached to a split lead
frame with two die attach paddles. For the purposes of thermal
analysis, the chip is treated as a thermal unit, with the highest
junction temperature reflected in the θJA from Table 8. The value
of θJA is based on measurements taken with the parts mounted
on a JEDEC standard, 4-layer board with fine width traces and
still air. Under normal operating conditions, the ADuM6010
can operate at full load across the full temperature range without
derating the output current.
Bipolar ac voltage is the most stringent environment. A 50-year
operating lifetime under the bipolar ac condition determines
the Analog Devices recommended maximum working voltage.
Power dissipation in the part varies with ambient temperature
due to the characteristics of the switching and rectification
elements. Figure 14 and Figure 15 show the relationship
between total power dissipation at two load conditions
and ambient temperature. This information can be used
to determine the junction temperature at various operating
conditions to ensure that the part does not go into thermal
shutdown unexpectedly.
In the case of unipolar ac or dc voltage, the stress on the insulation
is significantly lower. This allows operation at higher working
voltages while still achieving a 50-year service life. The working
voltages listed in Table 14 can be applied while maintaining the
50-year minimum lifetime, provided the voltage conforms to either
the unipolar ac or dc voltage cases. Any cross-insulation voltage
waveform that does not conform to Figure 20 or Figure 21 must
be treated as a bipolar ac waveform, and its peak voltage must
be limited to the 50-year lifetime voltage value listed in Table 14.
EMI CONSIDERATIONS
The dc-to-dc converter section of the ADuM6010 components
must, of necessity, operate at a very high frequency to allow
efficient power transfer through the small transformers. This
creates high frequency currents that can propagate in circuit
board ground and power planes, causing edge and dipole
radiation. Grounded enclosures are recommended for applica-
tions that use these devices. If grounded enclosures are not
possible, follow good RF design practices in the layout of the
PCB. See the AN-0971 Application Note at www.analog.com for
the most current PCB layout recommendations for the ADuM6010.

All insulation structures eventually break down when subjected to
voltage stress over a sufficiently long period. The rate of insulation
degradation is dependent on the characteristics of the voltage
waveform applied across the insulation. Analog Devices conducts
an extensive set of evaluations to determine the lifetime of the
insulation structure within the ADuM6010.

NOTES
Accelerated life testing is performed using voltage levels higher
than the rated continuous working voltage. Acceleration factors for
several operating conditions are determined, allowing calculation
of the time to failure at the working voltage of interest. The values
shown in Table 14 summarize the peak voltages for 50 years of
service life in several operating conditions. In many cases, the
