TPS7H6015-SEP: Can TPS7H5007 withTPS7H6015 drive a synchronous-boost converter?

Part Number: TPS7H6015-SEP
Other Parts Discussed in Thread: TPS7H5007-SEP, , TPS7H6015-SP

Tool/software:

Hello,

Is it possible to implement a synchronous boost converter using TPS7H5007-SEP PWM controller and TPS7H6015-SEP as gate driver?
If yes, how should the driver be connected to control both the main switch and the synchronous-rectifier MOSFET?

Thank you

    Hey Alexandre,

    To make a synchronous boost converter with the two parts you listed, you would simply use the IIM mode of the TPS7H6015-SEP.

    In this mode you could connect the synchronous output (SRA) of the TPS7H5007-SEP to the TPS7H6015-SP high side and main output (OUTA) to the low side.

    Thanks,
    Daniel
