PWR-TOP200YAI 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-05012 transformer has been optimized to provide maximum power throughput. The PWR-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 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, 6 watt application circuit utilizing Power Integrations PWR-TOP200 switching regulator in the flyback buck-boost configuration. The component values listed are intended for reference purposes only. This circuit provides +5Vdc at 1.20Amp continuous and is capable of >1.40Amps peak for short periods of time. The voltage feedback loop is closed to the +5V output via the opto coupler thus providing a high precision 5V output. If line and load regulation of 8-10% can be tolerated please refer to Premier's POL-05010 data sheet for a simpler circuit implementation.
