The Future of Analog IC Technology
DESCRIPTION
The MP2312 is a fully integrated high frequency
synchronous rectified step-down switch mode
converter. It offers very compact solutions to
achieve 2.1A continuous output current over a
wide input supply range with excellent load and
line regulation. The MP2312 operates at high
efficiency over a wide output current load range.
Constant-On-Time (COT) control mode
provides fast transient response and eases loop
stabilization.
Under voltage lockout is internally set as 4.6 V,
An open drain power good signal indicates the
output is within its nominal voltage range.
Full protection features include OCP and thermal
shut down.
The converter requires minimum number of
external components and is available in QFN16
(3x3mm) package.
