1 / 17 page © Semiconductor Components Industries, LLC, 2006 August, 2006 − Rev. 3 1 Publication Order Number: NCP1522/D 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 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 • 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 • 60 mA Quiescent Current (Typ) • Synchronous Rectification for Higher Efficiency • 2.7 V to 5.5 V Input Voltage Range • Thermal Limit Protection • Shutdown Current Consumption of 0.3 mA • Short Circuit Protection • This is a Pb−Free Device Typical Applications • Cellular Phones, Smart Phones and PDAs • MP3 Players and Portable Audio Systems • Wireless and DSL Modems • Portable Equipment • USB Powered Devices • Digital Still/Video Cameras GND 2 VIN 1 EN 3 LX 5 FB 4 OFF ON VIN CIN COUT R1 R2 Cff Figure 1.
