NCP1521BSNT1G產(chǎn)品概述

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 TSOP-5 and UDFN-6 packages.
