Buck Converter - DC-DC, High Efficiency, Adjustable Output Voltage, Low Ripple 1.7 MHz, 1 A NCP1529 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.
