The Future of Analog IC Technology
19V, 3A, 40µA IQ, High-Efficiency
Constant On-Time (COT) Step-Down
Converter in 2x3mm QFN Package
The MP2316 is a fully-integrated, high efficiency,
synchronous, step-down switch-mode converter,
featuring only 40μA quiescent current. This very
compact device achieves 3A continuous output
current over a wide input supply range with
excellent load and line regulation, and can
operate with high efficiency over a wide output
current load range. It’s optimized for battery-
operated applications and applications requiring
high light load efficiency.
With Constant On-Time control, the MP2316
provides very fast transient response, easy loop
design as well as very tight output regulation.
Full protection features include SCP, OCP, UVP,
and thermal shutdown.
The MP2316 requires a minimal number of
readily available standard external components
with a space saving 2mmx3mm 14-pin QFN
