MP2130
DESCRIPTION
The MP2130 is a monolithic step-down switch
mode converter with built-in internal power
MOSFETs. It achieves 3.5A continuous output
current from a 2.7V to 6V input voltage with
excellent load and line regulation. The MP2130 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 Constant-On-time (COT) control scheme
provides fast transient response high light-load
efficiency and easy loop stabilization.
Fault condition protection includes cycle-by-cycle
current limit and thermal shutdown.
The MP2130 requires a minimum number of readily
available standard external components and is
available in an ultra-small QFN12 (2x2mm)
package.
The MP2130 is ideal for a wide range of
applications including PDAs, portable instruments,
DVD drives, small handhold and battery–powered
devices.
