MP2338GTL集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

MP2338GTL属于集成电路（IC）的稳压器-DC-DC开关稳压器。由美国芯源系统有限公司制造生产的MP2338GTL稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。

DESCRIPTION

The MP2338 is a fully integrated, highfrequency,

synchronous, rectified, step-down

switch-mode converter with internal power

MOSFETs. It offers a very compact solution to

achieve 3A of continuous output current across

a wide input range, with excellent load and line

regulation. The MP2338 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 MP2338 requires a minimal number of

readily available, standard external components.

It is available in a space-saving SOT583

package.
