description

The high performance TPS56300 synchronous-buck regulator provides two supply voltages to power the core

and I/O of digital signal processors, such as the 鈥楥6000 family. The ripple regulator, using hysteretic control with

droop compensation, is configured for the core voltage and features fast transient response time reducing

output bulk capacitance (continued).
