GENERAL DESCRIPTION
The MT3410LB is high-efficiency,high frequency
synchronous step-down DC-DC regulator ICs
capable of delivering up to 1.3A output
currents.The MT3410LB can operate over a wide
input voltage range from 2.3V to 7V and integrates
main switch and synchronous switch with very
low RDS(ON) to minimize the conduction loss.
It is ideal for powering portable equipment that
runs from a single cell Lithium-Ion(Li+)
battery.The output voltage can be regulated as low
as 0.6V.The MT3410LB can also run at 100% duty
cycle for low dropout operation,extending battery
life in portable system.This device offers two
operation modes,PWM mode and PFM mode
switching control,which allows a high efficiency
over the wide range of the load.
The MT3410LB is offered in a low profile 5-pin
SOT package,and is available in an adjustable
version.
