Overview

UNISONIC TECHNOLOGIES CO.
, LTD UC3555 Advance 500MA HIGH EFFICIENCY BOOST REGULATOR WITH ADJUSTABLE OUTPUT, SHUTDOWN AND LOW BATTERY DETECT  DESCRIPTION The UC3555 is a micropower step-up DC/DC in 8-lead TSSOP package.
It is designed for 2-cell battery powered systems such as digital cameras, cell phones and PDAs.
The regulator starts-up at 1.
3V and operates after the start at an input voltage as low as 1V.
A Minimum off-time, variable on-time control scheme provides high efficiency over a wide range of load conditions.
The combination of build-in power transistors, synchronous rectification, low battery detection and low supply current, make the UC3555 ideal for portable applications.
