GENERAL DESCRIPTION

The MT3410L is high-efficiency,high frequency

synchronous step-down DC-DC regulator ICs

capable of delivering up to 1.3A output

currents.The MT3410L can operate over a wide

input voltage range from 2.3V to 6V 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 MT3410L 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 MT3410L is offered in a low profile 5-pin SOT

package,and is available in an adjustable version.
