NCP1521BSNT1G Power Switching Regulator NCP1521 SOT23-5 Buck Converter DC-DC 1.5 MHz 600 mA

NCP1521B Buck Converter - DC-DC 1.5 MHz, 600 mA

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.
