MP2328中文资料美国芯源数据手册PDF规格书

DESCRIPTION

The MP2328 is a fully integrated, highfrequency, synchronous, rectified, step-down

switch-mode converter with internal power

MOSFETs. It offers a very compact solution to

achieve 2A of continuous output current across

a wide input range, with excellent load and line

regulation. The MP2328 has synchronous

mode operation for high efficiency across the

wide output current load range.

Constant-on-time (COT) control provides very

fast transient response and easy loop design,

as well as tight output regulation.

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage protection (UVP), and thermal

shutdown.

The MP2328 requires a minimal number of

readily available, standard external components.

It is available in a space-saving SOT583

package.
