Synchronous Buck Converter

DESCRIPTION
The MP2106 is a 1.5A, 800KHz synchronous
buck converter designed for low voltage
applications requiring high efficiency. It is
capable of providing output voltages as low as
0.9V, and integrates top and bottom switches to
minimize power loss and component count. The
800KHz switching frequency reduces the size
of filtering components, further reducing the
solution size.
The MP2106 includes cycle-by-cycle current
limiting and under voltage lockout. The internal
power switches, combined with the tiny 10-pin
MSOP and QFN packages, provide a solution
requiring a minimum of surface area.
