SC221数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The SC221 is a 20MHz X-EMI™(1)-enabled step-down regulator optimized for power low voltage rails from 2.7 to 5.5V input voltage. X-EMI™ inductor technology enables inductors to be drawn directly on the PC board. This technology meets or exceeds the EMI performance of chip inductors and eliminates the need for discrete inductors.

简介

SC221属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的SC221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。
