TOP223Y three terminal off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. This conversion topology can provide isolated multiple outputs with efficiencies up to 90%. Premier's TSD-1144transformer has been optimized to provide maximum power throughput. The TOPXXX series from Power Integrations, Inc. are self contained 100KHz three terminal voltage controlled PWM switching regulators. This part contains all necessary functions for an off-line switched mode control DC power source. This switching regulator provides a very simple solution for off-line designs. The inductors and transformer used with the 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 24 watt application circuit utilizing Power Integrations TOP223Y switching regulator in the flyback buck-boost configuration. Careful breadboard evaluation must be completed to define overall circuit performance in the actual application. The component values listed are intended for reference purposes only.
