Burr-Brown Corporation
offers the world's smallest and
most reliable isolated DC/DC Converters with a wide variety
of input and output voltages. The introduction of the
ground-breaking DCP01 1 Watt converter heralded the
beginning of DC/DC converters available in standard
semiconductor packaging--power as a component! Available in
both 14-pin PDIP and surface mount, these products are ideal
for high volume tape and reel assembly processes.
The newly released DCP02 family of 2 Watt converters sets a
new industry standard by offering an unmatched combination
of reliability, power density and small package size--SO-28.
All of this is made possible by Burr-Brown Corporation's
unique manufacturing process known as "Integrated
Lead-Frame Technology". This removes the need for substrates
and unreliable solder joints within the device package,
bringing high volume semiconductor manufacturing techniques
to the Isolated Power market together with inherent, proven
high reliability.
Burr-Brown Corporation is committed to the further
development of its DC/DC Converter range, with higher
power and application specific products, combining the
manufacturing and silicon design expertise of the Company to
produce reliable, cost effective and high performance products.

The simplest configuration for the DCP family of DC/DC
Converters is a single voltage in and a single voltage out.
Shown here is a 5V to 5V conversion.
Higher power can be achieved by combining devices. A
4-Watt circuit is shown, with dual output rails. Both
devices are synchronized to reduce noise and
radiated emissions.
Unusual voltages can be generated by combining the
output voltages of two devices. The additive effect makes
possible a wide variety of outputs.

Isolated DC/DC Converters
Reliability
As can be seen above, the DCP and DCR families of
products are manufactured using semiconductor
assembly techniques. This ensures that the products have
the highest reliability in the market.
Our commitment to provide the highest performance and
most reliable products is shown by our investment in
design and the many approvals by internationally
recognized standards. For example, a figure of 75 FITS
has already been demonstrated.
Full vibration testing to MIL-STD-883 Method 2007.2 has
been completed to ensure the robustness of the assembly.
Device Approvals
Safety isolation testing has been done to the requirements
of UL1950. This involves testing at 1000Vrms or
1500Vrms for one minute as appropriate to prove the
device. During production, a one second flash test is
carried out.
Electro Magnetic Compatibility (EMC) testing to EN55022
Class B shows that the products exhibit excellent
performance for emissions and immunity.
Further details can be found in the relevant product data
sheet available from our website, www.Burr-Brown.com,
or from Burr-Brown representatives and distributors.
Semiconductor manufacturing techniques allow
cost effective, high volume manufacturing.
Copper leadframe gives excellent
thermal performance.
Welded joints provide high reliability.
Custom controller IC for
maximum efficiency and
features.
Miniature magnetics allow the
use of true IC packages to
minimize size.
