NCP1521B

1.5 MHz, 600 mA Step-Down

DC-DC Converter

High−Efficiency, Low Ripple, Adjustable

Output Voltage

The NCP1521B 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

3.9 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 1.5 MHz (nominal) oscillator which reduces component

size by allowing smaller inductors and capacitors. Automatic switching

PWM/PFM mode offers improved system efficiency.

Additional features include integrated soft−start, cycle−by−cycle

current limiting and thermal shutdown protection. The NCP1521B is

available in a space saving, low profile TSOP5 and UDFN6 packages.

Features

• Up to 96% Efficiency
