MP2236
18V, 6A, High-Efficiency,
Synchronous Step-Down Converter
DESCRIPTION
The MP2236 is a high-frequency, synchronous,
rectified, step-down, switch-mode converter.
The MP2236 offers a fully integrated solution
that achieves 6A of continuous output current
with excellent load and line regulation over a
wide input supply range.
Constant-on-time (COT) control operation
provides fast transient response. Full protection
features include hiccup over-current protection
(OCP) and thermal shutdown.
The MP2236 requires a minimal number of
readily available, standard, external
components and is available in a space saving
8-pin TSOT23 package.
