Part: NCP1522ASNT1G
Category:
Power Management
-> DC-DC Converters
-> Step-down
Description: 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 component size by allowing a small inductor and capacitors. Automatic switching PWM/PFM mode offers improved system efficiency. Finally, it includes an integrated soft−start, cycle−by−cycle current limiting, and thermal shutdown protection. The NCP1522 is available in a space saving, low profile TSOP5 package. <<<>>>Features and Applications <<<>>>Features <<<>>>93.8% of Efficiency for 3.3 V Output and 4.5 V Input and 120 mA Load Current <<<>>>Sources up to 600 mA <<<>>>3.0 MHz Switching Frequency <<<>>>Adjustable Output Voltage from 0.9 V to 3.3 V <<<>>>Autoswitching PWM/PFM mode at light load conditions <<<>>>Short Circuit Protection <<<>>>60 uA Quiescent Current (Typ) <<<>>>-30C to 85C Operation Temperature <<<>>>low profile TSOP5 package 3x3mm <<<>>>Pb Free package <<<>>>Applications <<<>>>Cellular Phones, Smart Phones and PDAs <<<>>>MP3 Players and Portable Audio Systems <<<>>>Digital Still/Video Cameras <<<>>>USB Powered Devices <<<>>>Wireless and DSL Modems <<<>>>Portable Equipment
