Hi,

I'm designing a CPU/FPGA board with multiple voltage rails, ranging from 0.9 V to 5 V. I'm thinking about using the UDC9240 controller and Powertrain modules. However, the Powertrain modules can't supply 5 V out. How should I solve the 5 V out power supply? I would like the 5 V rail to be controlled by the UDC9240 also, so that I can sequence and monitor it through the same controller interface. (Input voltage is 12 V.)

Thanks,

Lukas

    TI now has a driver with integrated mosfets which can implement 5V and higher POL phases, it is the UCD7242.

    It is capable of implementing two phases of up to 10 amps each.
