GENERAL DESCRIPTION
The ADuM6020 and ADuM60281 are isoPower®, integrated,
isolated dc-to-dc converters. Based on the Analog Devices, Inc.,
iCoupler® technology, these dc-to-dc converters provide
regulated, isolated power that is below CISPR22 Class B limits at
full load on a 2-layer printed circuit board (PCB) with ferrites.
Common voltage combinations and the associated current
output levels are shown in Table 1 through Table 4.
The ADuM6020 and ADuM6028 isolated dc-to-dc converters
provide two different package variants: the ADuM6020 in a
wide body, 16-lead SOIC_IC package, and the ADuM6028 in
the space saving, 8-lead, wide body SOIC_IC package. For 5 V
input operations, use the ADuM6020-5BRWZ and the
ADuM6028-5BRIZ. For 3.3 V input to 3.3 V output operations,
use the ADuM6020-3BRWZ and the ADuM6028-3BRIZ. See
the Pin Configuration and Function Descriptions section and
the Ordering Guide for more information.
The ADuM6020 and ADuM6028 eliminate the need to design
and build isolated dc-to-dc converters in applications up to
500 mW. The iCoupler chip scale transformer technology is used
for the magnetic components of the dc-to-dc converter. The
result is a small form factor, isolated solution.

ADuM6020/ADuM6028
THEORY OF OPERATION
The ADuM6020/ADuM6028 dc-to-dc converters work on
principles that are common to most standard power supplies.
The converters have a split controller architecture with isolated
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 3.3 V
or 5.0 V, depending on the setting of the VSEL pin. Note that the
ADuM5020-3BRWZ and the ADuM5028-3BRIZ can only be
used for 3.3 V input to 3.3 V output applications, and the
ADuM5020-5BRWZ and the ADuM5028-5BRIZ operate best at
5 V input applications. 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
significantly higher power and efficiency.
The ADuM6020/ADuM6028 implement undervoltage lockout
(UVLO) with hysteresis on the primary and secondary side input
and output pins as well as the VDDP power input. The UVLO
feature ensures that the converters do not go into oscillation
due to noisy input power or slow power-on ramp rates.

These capacitors are most conveniently connected between the
PCB LAYOUT
The ADuM6020 and ADuM6028 isoPower integrated dc-to-
dc converters require power supply bypassing at the input and
output supply pins (see Figure 21 and Figure 22). Low effective
series resistance (ESR) 0.1 μF bypass capacitors are required
between the VDDP pin and GND1 pin, as close to the chip pads
as possible. Low ESR 0.1 μF or 0.22 μF capacitors are required
between the VISO pin and GNDISO pin, as close to the chip pads
as possible (see the CISO note in Figure 23 and Figure 24 for
more information). The isoPower inputs require multiple
passive components to bypass the power effectively, as well
as set the output voltage and bypass the core voltage regulator
(see Figure 21 through Figure 26).
VDDP pin and GND1 pin, and between the VISO pin and GNDISO pin.
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 VDDP. The smaller capacitor must have a
low ESR. For example, use of a ceramic capacitor is advised. The
total lead length between the ends of the 0.1 ꢀF low ESR
capacitors, and the power supply pins must not exceed 2 mm.
To reduce the level of electromagnetic radiation, the impedance
to high frequency currents between the VISO and GNDISO pins and
the PCB trace connections can be increased. Using this method
of electromagnetic interference (EMI) suppression controls the
radiating signal at its source by placing surface-mount ferrite
beads in series with the VISO and GNDISO pins, as shown in
Figure 25 and Figure 26. The impedance of the ferrite bead is
chosen to be about 1.8 kΩ between the 100 MHz and 1 GHz
frequency range to reduce the emissions at the 180 MHz primary
switching frequency and the 360 MHz secondary side rectifying
frequency and harmonics. See Table 20 for examples of appropriate
surface-mount ferrite beads.

provide adequate lifetime with smaller creepage. The minimum
creepage for a given working voltage and material group is in
each system level standard and is based on the total rms voltage
across the isolation, pollution degree, and material group. The
material group and creepage for the ADuM6020 and ADuM6028
are presented in Table 8 and Table 9.
THERMAL ANALYSIS
The ADuM6020 and ADuM6028 each consist of three internal
die attached to a split lead frame. For thermal analysis, the die is
treated as a thermal unit, with the highest junction temperature
reflected in the θJA values, shown in Table 10 and Table 11. The
value of θJA is based on measurements taken with the devices
mounted on a JEDEC standard, 4-layer board with fine width
traces and still air. Under normal operating conditions, the
ADuM6020 and ADuM6028 can operate at full load, but at
temperatures greater than 85°C, derating the output current
may be needed, as shown in Figure 3 and Figure 4.
Insulation Wear Out
The lifetime of insulation caused by wear out is determined by
its thickness, material properties, and the voltage stress applied.
It is important to verify that the product lifetime is adequate at
the application working voltage. The working voltage supported
by an isolator for wear out may not be the same as the working
voltage supported for tracking. The working voltage applicable
to tracking is specified in most standards.
Testing and modeling show that the primary driver of long-term
degradation is displacement current in the polyimide insulation
causing incremental damage. The stress on the insulation can be
grouped into broad categories, such as dc stress, which causes very
little wear out because there is no displacement current, and an
ac component time varying voltage stress, which causes wear out.
EMI CONSIDERATIONS
The ADuM6020/ADuM6028 dc-to-dc converters must, of
necessity, operate at a high frequency to allow efficient power
transfer through the small transformers. This high frequency
operation creates high frequency currents that can propagate in
circuit board ground and power planes, requiring proper power
supply bypassing at the input and output supply pins (see Figure 25
and Figure 26). Using proper layout, bypassing techniques, and
surface-mount ferrite beads in series with the VISO and GNDISO
pins, the dc-to-dc converters are designed to provide regulated,
isolated power that is below CISPR22 Class B limits at full load
on a 2-layer PCB with ferrites.
The ratings in certification documents are usually based on a
60 Hz sinusoidal waveform because this stress reflects isolation
from line voltage. However, many practical applications have
combinations of 60 Hz ac and dc across the barrier as shown in
Equation 1. Because only the ac portion of the stress causes
wear out, the equation can be rearranged to solve for the ac rms
voltage, as shown in Equation 2. For insulation wear out with the
polyimide materials used in these products, the ac rms voltage
determines the product lifetime.
INSULATION LIFETIME
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, as well as on the materials
and material interfaces.

or

The two types of insulation degradation of primary interest are
breakdown along surfaces exposed to the air and insulation wear
out. Surface breakdown is the phenomenon of surface tracking
and the primary determinant of surface creepage requirements
in system level standards. Insulation wear out is the phenomenon
where charge injection or displacement currents inside the
insulation material cause long-term insulation degradation.

RMS is the total rms working voltage.
AC RMS is the time varying portion of the working voltage.
DC is the dc offset of the working voltage.
Calculation and Use of Parameters Example
The following example frequently arises in power conversion
applications. Assume that the line voltage on one side of the
isolation is 240 V ac rms and a 400 V dc bus voltage is present
on the other side of the isolation barrier. The isolator material is
polyimide. To establish the critical voltages in determining the
creepage, clearance, and lifetime of a device, see Figure 27 and
the following equations.
Surface Tracking
Surface tracking is addressed in electrical safety standards by
setting a minimum surface creepage based on the working voltage,
the environmental conditions, and the properties of the insulation
material. Safety agencies perform characterization testing on the
surface insulation of components that allows the components to be
categorized in different material groups. Lower material group
ratings are more resistant to surface tracking and, therefore, can

To determine if the lifetime is adequate, obtain the time varying
portion of the working voltage. To obtain the ac rms voltage,
use Equation 2.

In this case, the ac rms voltage is simply the line voltage of
240 V rms. This calculation is more relevant when the waveform is
not sinusoidal. The value is compared to the limits for working
voltage in Table 16 for the expected lifetime, which is less than a
60 Hz sine wave, and it is well within the limit for a 50-year
service life.

Note that the dc working voltage limit is set by the creepage of
the package as specified in IEC 60664-1. This value can differ
for specific system level standards.

This VRMS value is the working voltage used together with the
material group and pollution degree when looking up the creepage
required by a system standard.
