GENERAL DESCRIPTION
The MT1470 is a fully integrated, high efficiency
2A synchronous rectified step-down converter.
The MT1470 operates at high efficiency over a
wide output current load range.
This device offers two operation modes, PWM
control and PFM Mode switching control, which
allows a high efficiency over the wider range of the
load.
The MT1470 requires a minimum number of
readily available standard external components
and is available in an 6-pin SOT23 ROHS
compliant package
