NCP1522B Buck Converter - DC-DC 3 MHz, 600 mA The NCP1522B step−down DC−DC converter is a monolithic integrated circuit optimized for portable applications powered from one cell Li−Ion or three cell Alkaline/NiCd/NiMH batteries. The part, available in adjustable output voltage versions ranging from 0.9 V to 3.3 V, is able to deliver up to 600 mA. It uses synchronous rectification to increase efficiency and reduce external part count. The device also has a built−in 3 MHz (nominal) oscillator which reduces component size by allowing smaller inductors 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.
