Premier Magnetics' off-line switch mode transformers have been designed for use with Power Integrations' 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 optimised 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 Premier Magnetics, Inc.'s PWR-TOPXXX are critical to the performance of the circuit. They define the overall efficiency, output power and overall physical size.
