DESCRIPTION
The MP2238 is a high frequency, synchronous,
rectified, step-down switch-mode converter. It
offers a fully integrated solution to achieve an
8A 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
and thermal shutdown.
The MP2238 requires a minimal number of
readily available, standard, external
components with a space-saving 12-pin QFN
2mmx3mm package.
