TBSG25-40 Datasheet

DC-DC Power Converters
1

Hi MPS Team,

I am working with the EVL8030-QJ-00B reference design and would like to get more information about the transformer T1 (Chengdu Jinzhichuan TBSG25-40).

I couldn’t find a datasheet or transformer specifications in the available documentation, and I have not received a response from technical support so far.

Could anyone share the datasheet or key transformer parameters (turns ratio, inductance, core type, etc.)?

Thank you.

Hello @vinhphamcong17

In the EVL8030-QJ-00B datasheet you can find some of the key transformer parameters that you are looking for about the TBSG25-40 Transformer (Inductance, Turns Ratio, and Core Type)

I also provide a winding diagram for further reference

Lastly, here are some extra electrical characteristics of this transformer:
Inductance: 55uH +/-10% [Tested Condition: 100kHz 1V 25degC)
Leakage: 1.0uH MAX

Regards,
Edgar
