产品概述

           CXSU6342 Series is a PWM Step-up DC/DC converter IC with low supply current by CMOS process. High frequency noise that occurs during switching is reduced by using advanced circuit designed, output voltage is programmable in 0.1V steps between 2.0~5.0V and maximum frequency is 100KHz(Typ.). A low ripple, high efficiency step-up DC/DC converter can be constructed of CXSU6342AxxX with only three external components. Also available is a CE(chip enable) function that reduce power dissipation During shut-down mode., and an independent Vdd pin function (separated power supply and voltage detect pins) for fly-back circuits.An inner soft-start circuit limits current surges from input power supply at start up and the reliability of the chip is improved. CXSU6342XxxX is suitable for use with battery-powered instrummets with low noise and low supply current.BtP嘉泰姆
