BD9S402MUF-CE2集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

BD9S402MUF-CE2属于集成电路（IC）的稳压器-DC-DC开关稳压器。由罗姆半导体集团制造生产的BD9S402MUF-CE2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。

General Description

BD9S402MUF-C is a synchronous buck DC/DC converter

with built-in low ON resistor power MOSFETs. It can

provide current up to 4 A. Small inductor is applicable due

to high switching frequency of 2.2 MHz. It has fast transient

response performance due to current mode control. It has

a built-in phase compensation circuit. Applications can be

created with a few external components.
