The MT3410LB is high-efficiency,high frequencysynchronous step-down DC-DC regulator ICscapable of delivering up to 1.3A outputcurrents.The MT3410LB can operate over a wideinput voltage range from 2.3V to 7V and integratesmain switch and synchronous switch with verylow RDS(ON) to minimize the conduction loss.It is ideal for powering portable equipment thatruns from a single cell Lithium-Ion(Li%2B)battery.The output voltage can be regulated as lowas 0.6V.The MT3410LB can also run at 100% dutycycle for low dropout operation,extending batterylife in portable system.This device offers twooperation modes,PWM mode and PFM modeswitching control,which allows a high efficiencyover the wide range of the load.The MT3410LB is offered in a low profile 5-pinSOT package,and is available in an adjustableversion.
