The NCP1529 step−down DC−DC converter is a monolithic integrated circuit for portable applications powered from one cell Li−ion or three cell Alkaline/NiCd/NiMH batteries. The device is able to deliver up to 1.0 A on an output voltage range externally adjustable from 0.9 V to 3.9 V or fixed at 1.2 V or 1.35 V. It uses synchronous rectification to increase efficiency and reduce external part count.

The device also has a built−in 1.7 MHz (nominal) oscillator which reduces component size by allowing a small inductor and capacitors. Automatic switching PWM/PFM mode offers improved system efficiency. Additional features include integrated soft−start, cycle−by−cycle current limiting and thermal shutdown protection. The NCP1529 is available in a space saving, low profile 2x2x0.5 mm UDFN6 package and TSOP−5 package.
