TRANSFORMERS

Indicated Parts are UL1950 & CSA-950 Recognized under UL File# E162344

Designed for Use with Power Integrations IC's.

Designed to Meet UL1950/IEC950 Safety Standards.

GENERAL APPLICATION INFORMATION

Premier Magnetics' Off-Line Switch Mode Transformers have been designed for use with Power Integrations, Inc. TOPXXX

series of off-line PWM switching regulators in the Flyback Buck-Boost circuit configuration. This conversion topology can

provide isolated multiple outputs with efficiencies up to 90%. Premiers' Switching Transformers have been optimized to

provide maximum power throughput.

The TOPXXX series from Power Integrations, Inc. are self contained upto 132KHz 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 high precision 15V @ 2 Amps (30 watt) application circuit utilizing Power Integrations PWR-

TOP226 switching regulator in the flyback buck-boost configuration. The component values listed are intended for

reference purposes only. The soft start capacitor Css is optional depending on the specific application. Simpler topology

is possible depending on the line/load regulation required.

Design Engineering Support Available.

Multiple Configurations.
