STK428-610 ANFI PROJECT PT2317B PREANFI TOP249Y 2X30V SMPS SCHEMATIC CIRCUIT DIAGRAM

The amphitheater project has been successfully finalized. In the amplifier circuit, the STK428-610 integrated preamp circuit was utilized in conjunction with the PT2317B digital control. Additionally, a TOP249Y power source was designed for all components of the SMPS circuit. The SMPS power transformer used was ETD39, with specific winding information available on page 34 to 39. The SMPS circuit was efficiently prepared with minimal materials due to the MOSFET housed in the driver of TOP249Y. This SMPS design was accomplished using the PI Expert program.

Furthermore, you have the flexibility to employ the preamp and SMPS circuitry in various projects. To do so, it’s essential to review the datasheet files that match the different STK amplifier integrals. These datasheets will align with the PCB drawing designed for the amphitheater, which is compatible with numerous leg connections of various STK series auxiliary integrations.
