ABSTRACT:
A packaged power supply device (10) is configured to output multiple supply voltages, which are converted from a single input voltage (VIN). The packaged power supply device may can be configured as a DC/DC converter, which is operable to output each of the output supply voltages in a sequential manner, in accordance's with power up sequencing requirements of a processor-based system. The sequential output supply voltages may include: a fixed core supply voltage, a programmable core supply voltage, an input/output (I/O) supply voltage, and a logic supply voltage. These output supply voltages might be converted from an input voltage VIN, which has a wide continuous operational range (e.g., 14-50 VDC).
