Summary and Features
This document is an engineering prototype report describing a 20W power supply
utilizing a TOP247Y. This power supply will be used in a cook top application where the
maximum ambient temperature can reach 105C.
• 105C Ambient Operation
• TOP247Y operates at 66kHz to reduce switching losses and EMI filter size
• Compact PCB 7” X 3”
• High efficiency >85% at full load
The products and applications illustrated herein (including circuits external to the products and transformer
construction) may be covered by one or more U.S. and foreign patents or potentially by pending U.S. and foreign
patent applications assigned to Power Integrations.
