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 0.9V to 3.3V and can source totally up to 1.6A, 1.0A maximum per channel. Converters are running at 2.25MHz switching frequency which reduces component size by allowing the use of small inductor (down to 1uH) and capacitors and operates 180 degrees 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 soft-start, cycle-by-cycle 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 uDFN package.
