TIDA-01503: Outputs of the Flyback Transformer

Amr Elhadidy

Part Number: TIDA-01503

Hello,

the schematic of TIDA-01503 Shows that the ISO 5V is supplied from higher turns Ratio than the ISO 15V; is that correct? On sheet 1 they are connected to suitable transformer Output positions; 15V up and 5V down. However, on sheet2 the 5V is up and the 15V is down. Would you please check it? Thank you very much.

Regards,

Amr

Hello,

The schematic is correct because the 15V is between pin 8 and pin 13/14 and the 5V is between pin 10/11 and pin 13/14. Please refer to the schematic of the transformer https://www.we-online.com/catalog/datasheet/750343661.pdf?_ga=2.152966073.101020299.1580555468-264553166.1580555468.

Hello,

Thank you very much. That is fine the PCB has no errors. However, may I recommend if you please change the schematic to be also like the one in the datasheet. It might lead to unintended mistakes.

Kind Regards,

Amr
