This reference design takes into account the voltage, current, and start-up requirements of the TMS320F280x Digital Signal Processor (DSP) families. The operating input voltage ranges from 3.4 V to 6 V. This design is a high-efficiency solution that provides two voltage rails (1.8-V core supply and 3.3-V I/O supply) and an active-low reset signal to the DSP.
