Low Voltage Buck Controller
A fixed 200 kHz internal oscillator reduces external components so further reducing board space usage. A highly accurate (1 percent) 0.985V reference is utilized to generate an output voltage of 1V up to 3.3 V from a 5 V input. With a 12 V operating voltage, the NCP1570 is compatible for all standard computing applications. A synchronous V2 architecture delivers fast transient response (200 nanoseconds typical) to changes in load, and excellent line and load regulation.
