NCP1532 Dual, Output Step-Down Converter 2.25 MHz The NCP1532 dual step down DCDC converter is a monolithic integrated circuit dedicated to supply core and I/O voltages of new multimedia design in portable applications powered from 1 cell Li ion or 3 cell Alkaline / NiCd / NiMH batteries.

Both channels are externally adjustable from 0.9 V to 3.3 V and can source totally up to 1.6 A, 1.0 A maximum per channel.

Converters are running at 2.25 MHz switching frequency which reduces c
