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.)
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.
Im using a UCD9248 with the UCD7242 Driver and I will like to have a 5V out, do you have a ref desing with this?
