PWR-TOP209PFI 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%. Premiers' POL-07003 transformer has been optimized to provide maximum power throughput. The PWR-TOP209 from Power Integrations, Inc. is a self contained 70KHz 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 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, 2 watt application circuit utilizing Power Integrations PWR-TOP209 switching regulator in the flyback buck-boost configuration. This circuit provides +7.5Vdc at 265mA continuous and is capable of 300mA peak for short periods of time. This circuit represents the lowest cost implementation and utilizes the bias winding for feedback control. As such the line & load regulation are worse than that which could be achieved by utilizing an opto-coupler to sense the actual outputs. The component values listed are intended for reference purposes only.
