NCP1522 Datasheet | onsemi

.. NCP1522 3.0 MHz, 600 mA, High- Efficiency, Low Quiescent Current, Adjustable Output Voltage Step- Down Converter The NCP1522 step- down PWM DC- DC converter is optimized for portable applications powered from one cell Li- ion or three cell Alkaline/NiCd/NiMH batteries. The device is available in an adjustable output voltage from 0.9 V to 3.3 V. It uses synchronous rectification to increase efficiency and reduce external part count. The device also has a built- in 3.0 MHz (nominal) oscillator which reduces ponent size by allowing a small inductor and capacitors. Automatic switching PWM/PFM mode offers improved system efficiency. Finally, it includes an integrated soft-...
