APPLICATION NOTES
Premier Magnetics' TSD-2023 Switch Mode Transformer was designed for use with Power Integrations, Inc. TOP243Y
off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. This conversion topology can
provide isolated multiple outputs with efficiencies up to 95%. Premiers' TSD-2023 transformer has been optimized
to provide maximum power throughput.
Below is a universal input high precision 13.5 watt application circuit utilizing Power Integrations TOP243Y switching
regulator in the flyback buck-boost configuration. The component values listed are intended for reference
purposes only. Properly sized heat sinks for the TOP2XX & D3 as well as proper thermal management of the clamp
network are critical requirements for efficient and reliable operation. The TVS clamp VR1 may need to be modified
based on actual end circuit temperature rise considerations.
