The Future of Analog IC Technology
DESCRIPTION
The MP2371 is a monolithic step-down switch
mode converter with a built-in internal power
MOSFET. It achieves 1.8A continuous output
current over a wide input supply range with
excellent load and line regulation. Current mode
operation provides fast transient response and
eases loop stabilization. Fault condition
protection includes cycle-by-cycle current limiting
and thermal shutdown.
The MP2371 requires a minimum number of
readily available standard external components.
The MP2371 is available in a 2mm x 2mm QFN8
package.
