DRV2700: RGPR

Micael Ramos
Prodigy 10 points
Part Number: DRV2700

Tool/software:

Hello, i am trying to make a simpler design, with the DRV2700RGPR component, that resemble a DRV2700EVM-HV500, but the transformer ATB322515-0110 looks like inadequate and unrecommendable for new designs.

There are any sugestions for an alternative transformers?

Thank you for your attention.

    Hi Micael, 

    I would ask you to study section, 8.2.1.2 of the datasheet. it will help understand how to select this component.

    In general you want to select the turns ratio based on the desired output voltage, and the inductance will be a tradeoff of efficiency and output ripple

    In this case if you wish to copy the circuit you should find another transformer with the same 1:10 turns ratio and a similar inductance, however the device will be able to compensate for a different inductance value. anything between 3.3-22uH will be functional, but the output ripple and efficiency will be affected based on this inductance. 

    Regards,
