SC4525A集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

SC4525A属于集成电路（IC）的稳压器-DC-DC开关稳压器。由升特制造生产的SC4525A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。

描述 Description

The SC4525A is a constant frequency peak current-mode step-down switching regulator capable of producing 3A output current from an input ranging from 8V to 28V. The switching frequency of the SC4525A is programmable up to 2MHz, allowing the use of small inductors and ceramic capacitors for miniaturization, and high input/output conversion ratio. The SC4525A is suitable for next generation XDSL modems, high-definition TVs and various point of load applications.
