SI-8001FFE集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

SI-8001FFE属于集成电路（IC）的稳压器-DC-DC开关稳压器。由三垦电气株式会社制造生产的SI-8001FFE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 SI-8001FFE DC voltage regulator is a DC-to-DC buck convertor that attains an oscillation frequency of 300 kHz, and has an integrated miniaturized choke coil, allowing it to serve as a small, high efficiency power supply in a compact TO220F package.

Features and Benefits

• 3.5 A output current supplied in a small, through-hole mount power package

• High efficiency: 83 at VIN= 15 V, IO= 2.0 A,VO= 5 V

• Requires only six external components (optional soft start requires an additional capacitor)

• Oscillation circuit built-in (frequency 300 kHz typical)

• Constant-current mode overcurrent protection circuit and overtemperature protection circuit built-in

• Soft start function built-in (can be implemented as an on/off function; output-off state at low level)

• Low current consumption during output-off state

Applications include:

▪ DVD recorder

▪ FPD TV

▪ Telecommunications equipment

▪ Office automation equipment, such as printers

▪ On-board local power supply

▪ Output voltage regulator for second stage of SMPS (switched mode power supply)
