Dual Output Step-Down Converter 2.25 MHz High-Efficiency, Out Of Phase Operation, Low Quiescent Current, Source Up To 1.6 A

The NCP1532 dual step down DC/DC converter is a monolithic integrated circuit dedicated to supply core and I/O voltages of new Multimedia design in portable applications powered from 1cell Liion 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 component size by allowing the use of small inductor (down to 1 H) and capacitors and operates 180 out of phase to reduce large amount of current demand on the battery. Automatic switching PWM/PFM mode and synchronous rectification offer improved system efficiency. The device CAN also operate into fixed frequency PWM mode for low noise applications where low ripple and good load transients are required. Additional features include integrated softstart, cyclebycycle current limit and thermal shutdown protection. The device CAN also be synchronized to an external Clock signal in the range of 2.25 MHz. The NCP1532 is available in a space saving, ultra low profile 3x3 x 0.55 mm 10 pin DFN package. By ON Semiconductor
