In the designs of simple
low power off line switching mode power supplies, many design
engineers are using popular controller chips like the Power Integration's
TINYSWITCH and TOPSWITCH. These 3 terminal devices are simple
to use and minimizes the number of parts count. However, the design
engineers would need to built his or her own transformers, inductors
and chokes to work with these TINYSWITCH and TOPSWITCH controllers.
These could be a tedious task which involve ordering the correct
cores, bobbins, wires, tapes, winding and testing them, etc, During
the engineering design and prototype stage, engineers are always
short of time. These tasks can be very time consuming and cumbersome.
CWS recognizes these
needs. Therefore, CWS design engineers have designed and make
available transformers solutions that are optimized for TINYSWITCH
and TOPSWITCH applications.
Please click on the
"Listing and Specifications" for TINYSWITCH and TOPSWITCH
above to find the hundreds of these transformers. If you cannot
find the ones you need, please contact us, and we can custom built
the transformer for you.
These CWS designed
Off Line Switch Mode Transformers are suitable for Forward, Fly
back, Buck, Boost circuit configuration with multiple outputs
with efficiencies up to 90%. CWS' switching transformers are also
optimized to provide maximum power output.
TNYXXX and TOPXXX series controller chips are self-contained 100KHz
three terminal voltage controlled PWM switching regulators. They
contain all necessary functions required for an off-line switching
DC power source. The inductors, line filter and transformers used
with the TNYXXX and TOPXXX series are very important to the circuit's
performance. They define the overall physical size, output power
and efficiency of the product.
The transformer products
shown in the links above are available off the shelf. CWS can
supply them in small to large quantities. If you cannot find the
types you need, please call us and we will built a custom one
