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. This design can be easily adapted to fi - Optimizing Transient Response of Internally Compensated DC-DC Converters (Rev. A)PDF, 1.1 Mb, Revisión: A, Archivo publicado: mayo 11, 2015

When performing measurements on DC-DC converters using pulse frequency modulation(PFM)or any power save mode proper care must be taken to ensure that the measurements are accurate. An accurate PFM mode efficiency measurement is critical for systems which require high efficiency at low loads such as in smart home systems tablets wearables and metering.
