NCP1570 Description
NCP1570 Low Voltage Synchronous Buck Controller The NCP1570 is a low voltage buck controller. It provides the control for a DC−DC power solution producing an output voltage as low as 0.985 V over a wide current range. The NCP1570−based solution is powered from 12 V with the output derived from a 5 V supply.
