APPLICATION NOTES
Premier Magnetics' TSD-1093 Shielded Switch Mode Transformer was designed for use with Power Integrations,
Inc. PWR-TOP209P three terminal off-line PWM switching regulator or Motorolas MC33363A Switching Regulator
in the Flyback Buck-Boost circuit configuration. This conversion topology can provide isolated multiple outputs
with efficiencies up to 90%. Premiers' TSD-1084 transformer has been optimized to provide maximum power
throughput while allowing the use of either controller.
Below is a universal input, 1.9 watt application circuit utilizing Power Integrations TOP209, 70KHz switching
regulator in the flyback buck-boost configuration. This circuit provides +7.5Vdc at 250mA 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. The component values listed are intended for reference purposes
only. The maximum duty cycle has been designed for 46% allowing the MC33363A to be utilized without resistor
"RD". The MC33363A would utilize an RT=39K and a CT of 500pF. This sets the peak current limit of the SeneseFET
to about 250mA while providing a nominal 70KHz switching frequency.
