BD9874CP-V5E2集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

BD9874CP-V5E2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BD9874CP-V5E2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 BD9873,74CP-V5 single-channel step-down switching regulatorincorporates a Pch MOSFET capable, as well as circuitry that eliminates the need for external compensation – only a diode, coil, and ceramic capacitor are required – reducing board size significantly.
