GENERAL APPLICATION INFORMATION
Premier Magnetics' Off-Line Switch Mode Transformers have been designed for
use with Power Integrations, Inc. TOPXXX series of off-line PWM switching
regulators in the Flyback Buck-Boost circuit configuration. This conversion
topology can provide isolated multiple outputs with efficiencies up to 90%.
Premiers' Switching Transformers have been optimized to provide maximum power
throughput.
The TOPXXX series from Power Integrations, Inc. are self contained upto 132KHz
controlled PWM switching regulators. This series contains all necessary
functions for an off-line switched mode control DC power source. These
switching regulators provide a very simple solution to off-line designs. The
inductors and transformer used with the PWR-TOPXXX are critical to the
performance of the circuit. They define the overall efficiency, output power
and overall physical size.
Below is a universal input high precision 15V @ 2 Amps (30 watt) application
circuit utilizing Power Integrations PWR TOP226 switching regulator in the
flyback buck-boost configuration. The component values listed are intended for
reference purposes only. The soft start capacitor Css is optional depending on
the specific application. Simpler topology is possible depending on the
line/load regulation required.
*** Designed for Use with Power Integrations IC's.**
- Design Engineering Support Available.
- Designed to Meet UL1950/IEC950 Safety Standards.
- Multiple Configurations.
