description
The TPS56100 is a high-efficiency synchronous-buck regulator controller which provides an accurate
programmable supply voltage to low-voltage digital signal processors, such as the ‘C6x and ‘C54x DSPs. An
internal 5-bit DAC is used to program the reference voltage from 1.3 V to 2.6 V. Higher output voltages can be
implemented using an external input resistive divider. The TPS56100 uses a fast hysteretic control method that
provides a quick transient response. The propagation delay from the comparator input to the output driver is
application example
