FEATURES
GENERAL DESCRIPTION
isoPower integrated, isolated dc-to-dc converter
Regulated 5 V or 3.3 V output
Up to 400 mW output power
16-lead SOIC wide-body package (RW-16)
16-lead SOIC wide-body package with enhanced
creepage (RI-16-2)
High temperature operation: 105°C maximum
High common-mode transient immunity: >25 kV/μs
Thermal overload protection
The ADuM60001 is an isolated dc-to-dc converter based on the
Analog Devices, Inc., iCoupler® technology. The dc-to-dc converter
in this device provides regulated, isolated power in several combi-
nations of input and output voltages as listed in Table 1.
The Analog Devices chip scale transformer iCoupler technology
transfers isolated power in this dc-to-dc converter with up to
31% efficiency. The result is a small form factor, total isolation
solution.
Higher output power levels are obtained by using the ADuM6000
to augment the power output of the ADuM5401, ADuM5402,
ADuM5403, ADuM5404, ADuM520x, and ADuM620x iCouplers
with isoPower®.

Mnemonic Description
1, 7
VDD1
Primary Supply Voltage, 3.0 V to 5.5 V. Pin 1 and Pin 7 are internally connected to each other, and it is
recommended that both pins be externally connected to a common power source.
2, 8

other, and it is recommended that both pins be connected to a common ground.
3, 11, 12, 14 NC
No Internal Connection.
4
RCIN
Regulation Control Input. In slave power configuration (RCSEL low), this pin is connected to the RCOUT pin of a
master isoPower device, or it is tied low to disable the converter. In master or standalone mode (RCSEL high),
this pin has no function. This pin is weakly pulled to the low state. In noisy environments, it should be tied low
or tied to a PWM control source. This pin must not be tied high if RCSEL is low; this combination causes excessive
voltage on the secondary side of the converter, damaging the ADuM6000 and possibly the devices that it powers.

RCOUT
RCSEL
GNDISO
VISO
Regulation Control Output. In master power configuration (RCSEL high), this pin is connected to the RCIN pin of
a slave isoPower device to allow the ADuM6000 to regulate additional devices.
Control Input. Sets either standalone/master mode (RCSEL high) or slave mode (RCSEL low). This pin is weakly
pulled to the high state. In noisy environments, tie this pin either high or low.
Ground Reference for the Secondary Side of the Converter. Pin 9 and Pin 15 are internally connected to each
other, and it is recommended that both pins be connected to a common ground.
Secondary Supply Voltage Output for External Loads. 3.3 V (VSEL low) or 5.0 V (VSEL high). The 5.0 V output
functionality is not guaranteed for a 3.3 V primary supply input. Pin 10 and Pin 16 are internally connected
to each other, and it is recommended that both pins be externally connected.

VSEL
Output Voltage Selection. When VSEL = VISO, the VISO setpoint is 5.0 V. When VSEL = GNDISO, the VISO setpoint is 3.3 V.
This pin is weakly pulled to the high state. In noisy environments, tie this pin either high or low. In slave mode,
this pin has no function.

ADuM6000
Data Sheet
APPLICATIONS INFORMATION
The dc-to-dc converter section of the ADuM6000 works on
principles that are common to most switching power supplies. It
has a secondary side controller architecture with isolated pulse-
width modulation (PWM) feedback. VDD1 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 either 3.3 V or 5 V. The secondary
(VISO) side controller regulates the output by creating a PWM
control signal that is sent to the primary (VDD1) 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.
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. Best practice recommends using a
very low inductance ceramic capacitor, or its equivalent, for the
smaller value. The total lead length between both ends of the
capacitor and the input power supply pin should not exceed
10 mm. Consider bypassing between Pin 1 and Pin 8 and
between Pin 9 and Pin 16 unless both common ground pins
are connected together close to the package.

feature allows a single regulator to control multiple power mod-
ules without contention. When auxiliary power modules are
present, the VISO pins can be connected together to work as a
single supply. Because there is only one feedback control path,
the supplies work together seamlessly. The ADuM6000 can be
a source of regulation control (master mode), and it can also be
controlled by another isoPower device (slave mode).

Figure 14. Recommended PCB Layout
In applications involving high common-mode transients, ensure
that board coupling across the isolation barrier is minimized.
Furthermore, design the board layout such that any coupling that
does occur affects all pins equally on a given component side.
Failure to ensure this can cause voltage differentials between
pins exceeding the absolute maximum ratings for the device
as specified in Table 10, thereby leading to latch-up and/or
permanent damage.
The ADuM6000 implements undervoltage lockout (UVLO)
with hysteresis in the VDD1 input protection circuitry. When the
input voltage rises above the UVLO threshold, the dc-to-dc
converter becomes active. The input voltage must be decreased
below the turn-on threshold by the hysteresis value to disable
the converter. This feature has many benefits in the power-up
sequence of the converter. For example, UVLO ensures that the
system supply rises to a minimum level before the ADuM6000
demands current. Also, it prevents any voltage drop due to
converter current from turning the supply off and causing
oscillation.
The ADuM6000 is a power device that dissipates approximately
1 W of power when fully loaded. Because it is not possible to apply
a heat sink to an isolation device, the device primarily depends
on heat dissipation into the PCB through the GND pins. If the
device is used at high ambient temperatures, provide a thermal
path from the GND pins to the PCB ground plane. The board
layout in Figure 14 shows enlarged pads for Pin 2 and Pin 8
(GND1) and for Pin 9 and Pin 15 (GNDISO). Implement multiple
vias from the pad to the ground plane to significantly reduce the
temperature inside the chip. The dimensions of the expanded
pads are at the discretion of the designer and depend on the
available board space.
PCB LAYOUT
The ADuM6000 digital isolator is a 0.4 W isoPower integrated
dc-to-dc converter that requires no external interface circuitry
for the logic interfaces. Power supply bypassing is required at
the input and output supply pins (see Figure 14).
The power supply section of the ADuM6000 uses a 180 MHz
oscillator frequency to pass power efficiently through its chip
scale transformers. In addition, the normal operation of the
data section of the iCoupler introduces switching transients
on the power supply pins. Bypass capacitors are required for
several operating frequencies. Noise suppression requires a low
inductance, high frequency capacitor, whereas ripple suppression
and proper regulation require a large value capacitor. These
capacitors are most conveniently connected between Pin 1 and
START-UP BEHAVIOR
The ADuM6000 device does not contain a soft start circuit.
Therefore, the start-up current and voltage behavior must be
taken into account when designing with this device.
When power is applied to VDD1, the input switching circuit begins
to operate and draw current when the UVLO minimum voltage
is reached. The switching circuit drives the maximum available
power to the output until it reaches the regulation voltage where
PWM control begins. The amount of current and the time
required to reach regulation voltage depends on the load and
the VDD1 slew rate.

.

Data Sheet
ADuM6000
With a fast VDD1 slew rate (200 µs or less), the peak current draws
up to 100 mA/V of VDD1. The input voltage goes high faster than
the output can turn on, so the peak current is proportional to
the maximum input voltage.
CURRENT LIMIT AND THERMAL OVERLOAD
PROTECTION
The ADuM6000 is protected against damage due to excessive
power dissipation by thermal overload protection circuits.
Thermal overload protection limits the junction temperature to
a maximum of 150°C (typical). Under extreme conditions (that
is, high ambient temperature and power dissipation), when the
junction temperature starts to rise above 150°C, the PWM is
turned off, turning off the output current. When the junction
temperature drops below 130°C (typical), the PWM turns on
again, restoring the output current to its nominal value.
With a slow VDD1 slew rate (in the millisecond range), the input
voltage is not changing quickly when VDD1 reaches the UVLO
minimum voltage. The current surge is approximately 300 mA
because VDD1 is nearly constant at the 2.7 V UVLO voltage. The
behavior during startup is similar to when the device load is a
short circuit; these values are consistent with the short-circuit
current shown in Figure 7.
When starting the device for VISO = 5 V operation, do not limit
the current available to the VDD1 power pin to less than 300 mA.
The ADuM6000 device may not be able to drive the output to
the regulation point if a current-limiting device clamps the VDD1
voltage during startup. As a result, the ADuM6000 device can
draw large amounts of current at low voltage for extended
periods of time.
Consider the case where a hard short from VISO to ground occurs.
At first, the ADuM6000 reaches its maximum current, which is
proportional to the voltage applied at VDD1. Power dissipates on
the primary side of the converter (see Figure 7). If self-heating
of the junction becomes great enough to cause its temperature
to rise above 150°C, thermal shutdown is activated, turning off
the PWM and turning off the output current. As the junction
temperature cools and drops below 130°C, the PWM turns on
and power dissipates again on the primary side of the converter,
causing the junction temperature to rise to 150°C again. This
thermal oscillation between 130°C and 150°C causes the part
to cycle on and off as long as the short remains at the output.
The output voltage of the ADuM6000 device exhibits VISO
overshoot during startup. If this overshoot could potentially
damage components attached to VISO, a voltage-limiting device
such as a Zener diode can be used to clamp the voltage. Typical
behavior is shown in Figure 12 and Figure 13.
Thermal limit protections are intended to protect the device
against accidental overload conditions. For reliable operation,
externally limit device power dissipation to prevent junction
temperatures from exceeding 130°C.
EMI CONSIDERATIONS
The dc-to-dc converter section of the ADuM6000 must operate
at 180 MHz 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 emissions and dipole radiation between the primary and
secondary ground planes. Grounded enclosures are recommended
for applications 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 for board layout
recommendations.
POWER CONSIDERATIONS
The ADuM6000 converter primary side is protected from pre-
mature operation by undervoltage lockout (UVLO) circuitry.
Below the minimum operating voltage, the power converter
holds its oscillator inactive.
When the primary side oscillator begins to operate, it transfers
power to the secondary power circuits. The secondary VISO voltage
starts below its UVLO limit, making it inactive and unable to
generate a regulation control signal. The primary side power
oscillator is allowed to free run under this condition, supplying
the maximum amount of power to the secondary side.
THERMAL ANALYSIS
The ADuM6000 consists of four internal silicon die attached to
a split lead frame with two die attach paddles. For the purposes of
thermal analysis, it is treated as a thermal unit with the highest
junction temperature reflected in the θJA value from Table 5.
The value of θJA is based on measurements taken with the part
mounted on a JEDEC standard 4-layer board with fine width
traces and still air. Under normal operating conditions, the
ADuM6000 operates at full load across the full temperature
range without derating the output current. However, following
the recommendations in the PCB Layout section decreases the
thermal resistance to the PCB, allowing increased thermal
margin at high ambient temperatures.
As the secondary side voltage rises to its regulation setpoint, a
large inrush current transient is present at VDD1. When the regula-
tion point is reached, the regulation control circuit produces the
regulation control signal that modulates the oscillator on the
primary side. The VDD1 current is then reduced and is propor-
tional to the load current. The inrush current is less than the
short-circuit current shown in Figure 7. The duration of the
inrush current depends on the VISO loading conditions and on
the current and voltage available at the VDD1 pin.

INCREASING AVAILABLE POWER
The ADuM6000 device is designed to work in combination
with other compatible isoPower devices. The RCOUT, RCIN, and
RCSEL pins allow the ADuM6000 to provide its PWM signal to
another device through its RCOUT pin, acting as a master. It can
also receive a PWM signal from another device through its RCIN
pin and act as a slave to that control signal. The RCSEL pin chooses
whether the part acts as a master or slave device.

When the ADuM6000 acts as a slave, its power is regulated
by the master device, allowing multiple isoPower parts to be
combined in parallel while sharing the load equally. When the
ADuM6000 is configured as a master or standalone device, it
generates its own PWM feedback signal to regulate itself and
any slave devices.
ADuM5401 to
ADuM5404
Another feature that is allowed by the RCSEL and RCIN control
architecture is the ability to completely shut down the oscillator
in the dc-to-dc converter. This places the part in a low power
standby mode and reduces the current draw to a fraction of a
milliamp.
The ADuM6000 can function as a master, slave, or standalone
device. All devices in the ADuM5xxx and ADuM6xxx family
can function as standalone devices. Some of these devices also
function as master devices or slave devices, but not both (see
Table 14).
When the ADuM6000 is placed in slave mode by driving RCSEL
low, the oscillator is controlled by RCIN. If RCIN is held low, the
oscillator is shut down and the part is in low power standby
mode. With no oscillator driving power to the secondary side,
Table 15 illustrates how isoPower devices can provide many
combinations of data channel count and multiples of the single-
unit power.

ISO turns off. This mode is useful for applications where an
isolated subsystem may be shut down to conserve power. To
reactivate the power module, drive RCSEL high; the power supply
resumes operation.

ADuM6000
In the case of unipolar ac or dc voltage, the stress on the insu-
lation is significantly lower. This allows operation at higher
working voltages while still achieving a 50-year service life.
The working voltages listed in Table 11 can be applied while
maintaining the 50-year minimum lifetime, provided that the
voltage conforms to either the unipolar ac or dc voltage cases.
INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of insu-
lation degradation is dependent on the characteristics of the
voltage waveform applied across the insulation. In addition to
the testing performed by the regulatory agencies, Analog Devices
carries out an extensive set of evaluations to determine the life-
time of the insulation structure within the ADuM6000.
Any cross-insulation voltage waveform that does not conform
to Figure 16 or Figure 17 should be treated as a bipolar ac wave-
form and its peak voltage limited to the 50-year lifetime voltage
value listed in Table 11. The voltage presented in Figure 16 is
shown as sinusoidal for illustration purposes only. It is meant to
represent any voltage waveform varying between 0 V and some
limiting value. The limiting value can be positive or negative,
but the voltage cannot cross 0 V.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Accel-
eration factors for several operating conditions are determined.
These factors allow calculation of the time to failure at the actual
working voltage. The values shown in Table 11 summarize the
peak voltage for 50 years of service life for a bipolar ac operating
condition and the maximum CSA/VDE approved working volt-
ages. In many cases, the approved working voltage is higher than
the 50-year service life voltage. Operation at these high working
voltages can lead to shortened insulation life in some cases.

The insulation lifetime of the ADuM6000 depends on the
voltage waveform imposed across the isolation barrier. The

isolation voltage waveforms.
