TOP227Y three terminal off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. The TOPXXX series from Power Integrations, Inc. are self contained 100KHz three terminal voltage 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 TOPXXX are critical to the performance of the circuit. They define the overall efficiency, output power and overall physical size. Below is a universal (85Vac to 265Vac) input high precision 80 watt application circuit utilizing Power Integrations TOP227 switching regulator. This circuit provides three outputs. The "MAIN" output of secondary #1 is optically fed back to the TOP227 controller to close the voltage feedback loop. Secondary #2 & #3 are the slave outputs. The Bias is set to 19V and capable of .20A of Auxiliary power. The component values listed are intended for reference purposes only.
