NCP1522B Datasheet | onsemi

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 ponent size by allowing smaller inductors and capacitors. Automatic switching PWM/PFM mode offers improved system efficiency. Additional Features include integrated soft- start, cycle-...
