NCV2575D2T-5G集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

NCV2575D2T-5G属于集成电路（IC）的稳压器-DC-DC开关稳压器。由安森美半导体公司制造生产的NCV2575D2T-5G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。

The LM2575 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step−down switching regulator (buck converter). All circuits of this series are capable of driving a 1.0 A load with excellent line and load regulation.

These devices are available in fixed output voltages of 3.3 V, 5.0 V,12 V, 15 V, and an adjustable output version. These regulators were designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2575 are offered by several different inductor manufacturers.
