DESCRIPTION
The DCV01 series is a family of 1W, 1500Vrms
isolated, unregulated, isolated DC/DC converters. Re-
quiring a minimum of external components and in-
cluding on-chip device protection, the DCV01 series
provides extra features such as output disable and
synchronization of switching frequencies.
The use of a highly integrated package design results
in highly reliable products with a power density of
40W/in3 (2.4W/cm3). This combination of features
high isolation and small size makes the DCV01 suit-
able for a wide range of applications.

FUNCTIONAL DESCRIPTION
If synchronized devices are used, it should be noted that, at
start up, all devices will draw maximum current simulta-
neously. This can cause the input voltage to dip and should
it dip below the minimum input voltage (4.5V), the devices
may not start up. A 2.2µF capacitor should be connected
close to the input pins.
OVERVIEW
The DCV01 offers up to 1W of unregulated output power
with a typical efficiency of up to 85%. This is achieved
through highly integrated packaging technology and the
implementation of a custom power stage and control IC. The
circuit design utilizes an advanced BiCMOS/DMOS pro-
cess. Separate primary and secondary transformer windings
give good isolation and low barrier capacitance.
If more than eight devices are to be synchronized, it is
recommended that the SYNCIN pins are driven by an exter-
nal device. Details are contained in a separate applications
bulletin (AB-153).
POWER STAGE
This uses a push-pull, center-tapped topology switching at
400kHz (divide by 2 from 800kHz oscillator).
CONSTRUCTION
The DCV01’s basic construction is the same as standard ICs.
There is no substrate within the molded package. The
DCV01 is constructed using an IC, rectifier diodes, and a
wound magnetic toroid on a leadframe. As there is no solder
within the package, the DCV01 does not require any special
PCB assembly processing. This results in an isolated
DC/DC converter with inherently high reliability.
OSCILLATOR AND WATCHDOG
The onboard 800kHz oscillator generates the switching
frequency via a divide by 2 circuit. The oscillator can be
synchronized to other DCV01 circuits or an external source,
and is used to minimize system noise.
A watchdog circuit checks the operation of the oscillator
circuit. The oscillator can be stopped by pulling the SYNCIN
pin LOW. The output pins will be tri-stated. This will occur
in 2µs.
ADDITIONAL FUNCTIONS
DISABLE/ENABLE
The DCV01 can be disabled or enabled by driving the SYNC
pin using an open drain CMOS gate. If the SYNCIN pin is
pulled low, the DCV01 will be disabled. The disable time
depends upon the external loading; the internal disable func-
tion is implemented in 2µs. Removal of the pull down will
cause the DCV01 to be enabled.
THERMAL SHUTDOWN
The DCV01 is protected by a thermal shutdown circuit. If the
on-chip temperature exceeds 150°C, the device will shut
down. Once the temperature falls below 150°C, normal
operation will resume.
Capacitive loading on the SYNCIN pin should be minimized
in order to prevent a reduction in the oscillator frequency.
SYNCHRONIZATION
In the event that more than one DC/DC converter is needed
onboard, beat frequencies and other electrical interference
can be generated. This is due to the small variations in
switching frequencies between the DC/DC converters.
DECOUPLING
Ripple Reduction
The high switching frequency of 400kHz allows simple
filtering. To reduce ripple, it is recommended that at least a
1µF capacitor is used on VOUT. Dual outputs should both be
decoupled to pin 5. A 2.2µF low ESR capacitor on the input
of the 5V in versions, and a 0.47µF low ESR cap on the 24V
DCV01 in versions is recommended.
The DCV01 overcomes this by allowing devices to be
synchronized to one another. Up to eight devices can be
synchronized by connecting the SYNCIN pins together, tak-
ing care to minimize the capacitance of tracking. Stray
capacitance (> 3pF) will have the effect of reducing the

DCV01
The DCV01 is a switching power supply and as such can
place high peak current demands on the input supply. In
order to avoid the supply falling momentarily during the fast
switching pulses ground and power planes should be used to
track the power to the input of DCV01. If this is not possible
then the supplies must be connected in a star formation with
the tracks made as wide as possible.
Connecting the DCV01 in Series
Multiple DCV01 isolated 1W DC/DC converters can be
connected in series to provide nonstandard voltage rails.
This is possible by utilizing the floating outputs provided by
the DCV01’s galvanic isolation.
Connect the positive VOUT from one DCV01 to the negative
VOUT (0V) of another (see Figure 1). If the SYNCIN pins are
tied together, the self-synchronization feature of the DCV01
will prevent beat frequencies on the voltage rails. The
SYNCIN feature of the DCV01 allows easy series connec-
tion without external filtering, minimizing cost.
If the SYNCIN pin is being used then the tracking between
device SYNCIN pins should be short to avoid stray capaci-
tance. If the SYNCIN pin is not being used it is advisable to
place a guard ring, (connected to input ground) around this
pin to avoid any noise pick up.
The outputs on dual output DCV01 versions can also be
connected in series to provide two times the magnitude of
VOUT as shown in Figure 2. For example, a dual 15V DCV01
could be connected to provide a 30V rail.
The output should be taken from the device using ground
and power planes, this will ensure minimum losses.
A good quality low ESR capacitor placed as close as
practicable across the input will reduce reflected ripple and
ensure a smooth start up.
Connecting the DCV01 in Parallel
If the output power from one DCV01 is not sufficient, it is
possible to parallel the outputs of multiple DCV01s, as
shown in Figure 3. Again, the SYNCIN feature allows easy
synchronization to prevent power-rail beat frequencies at no
additional filtering cost.
A good quality low ESR capacitor placed as close as
practicable across the rectifier output terminal and output
ground will give the best ripple and noise performance.
THERMAL MANAGEMENT
Due to the high power density of this device it is advisable
to provide ground planes on the input and output.
PCB LAYOUT
Ripple and Noise
Careful consideration should be given to the layout of the
PCB in order that the best results can be obtained.
