Using Power Integration's TINYSWITCH and TOPSWITCH:
An Application Guide

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.

Power Integration's 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 for you.
