APPLICATION NOTES
Premier Magnetics' TSD-1406 Switch Mode Transformer was designed for use with Power Integrations, Inc.
TOP223P three terminal off-line PWM switching regulator in a low cost Isolated Flyback Buck-Boost circuit
configuration. The feedback implementation is accomplished indirectly by regulating the bias winding voltage.
This is the lowest cost topology but has the drawback of poor load regulation. As such this topology is intended
for use where load power is fairly constant. Resistor R2 provides an output clamp to prevent output voltage
runaway and possible circuit damage under a no load condition.
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 switch mode controlled 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 input 8 watt application circuit utilizing Power Integrations TOP223P switching regulator in the
isolated flyback buck-boost configuration. The component values listed are intended for reference purposes
only.
