描述 Description

Single-chip Type with Built-in FET Switching Regulators
Flexible Step-down Switching Regulator with Built-in Power MOSFET●Description
Output 3.0A and below High Efficiency Rate Step-down Switching Regulator Power MOSFET Internal Type BD9876EFJ mainly used as secondary side Power supply, for example fromfixed Power supply of 12V, 24Vetc, Step-down Output of 1.2V/1.8V/3.3V/5V, etc, can be produced. This IC has external Coil/Capacitor down-sizing through 300kHz Frequency operation, inside Nch-FET SW for 45V “withstand-pressure” commutation and also, high speed load response through
Current Mode Control is a simple external setting phase compensation system, through a wide range external constant, a compact Power supply can be produced easily.●

简介

BD9876EFJ属于集成电路（IC）的DCDC开关稳压器。由制造生产的BD9876EFJ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。
