DESCRIPTION

The

MP2236C

is

a

high-frequency,

synchronous, rectified, step-down, switch-mode

converter.

The

MP2236C

offers

a

fully

integrated solution that achieves up to 6A of

continuous output current (IOUT), with excellent

load and line regulation across 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 MP2236C requires a minimal number of

readily available, standard external components,

and is available in a space-saving TSOT23-8

package.
