Description
The NCP1521B is a monolithic integrated circuit optimized for portable applications powered from one-cell Li-Ion or three-cell Alkaline/NiCd/NiMH batteries. It is available in adjustable output voltage versions ranging from 0.9 V to 3.9 V and can deliver up to 600 mA. The NCP1521B uses synchronous rectification to increase efficiency and reduce external part count. It also has a built-in 1.5 MHz (nominal) oscillator which reduces component size by allowing smaller inductors and capacitors. Automatic switching PWM/PFM mode offers improved system efficiency.
Features
Up to 96% Efficiency
Best-In-Class Ripple, including PFM Mode
Sources up to 600 mA
1.5 MHz Switching Frequency
Adjustable Output Voltage from 0.9 V to 3.9 V
Synchronous Rectification for Higher Efficiency
2.7 V to 5.5 V Input Voltage Range
Low Quiescent Current
Shutdown Current Consumption of 0.3 μA
Thermal Limit Protection
Short Circuit Protection
All Pins are Fully ESD Protected
Applications
Cellular Phones, Smart Phones, and PDAs
Digital Still/Video Cameras
MP3 Players and Portable Audio Systems
Wireless and DSL Modems
Portable Equipment
USB Powered Devices
