BD9104FVM集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

BD9104FVM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BD9104FVM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。

● General Description

ROHM’s high efficiency step-down switching regulator (BD9102FVM, BD9104FVM, BD9106FVM) is a power supply designed to produce a low voltage including 1.24 volts from 5 volts power supply line. Offers high efficiency with our original pulse skip control technology and synchronous rectifier.

Employs a current mode control system to provide faster transient response to sudden change in load.

● Features

■ Offers fast transient response with current mode

PWM control system.

■ Offers highly efficiency for all load range with

synchronous rectifier (Nch/Pch FET)

and SLLMTM (Simple Light Load Mode)

■ Incorporates soft-start function.

■ Incorporates thermal protection and ULVO functions.

■ Incorporates short-current protection circuit with

time delay function.

■ Incorporates shutdown function

● Applications

Power supply for HDD, power supply for portable

electronic devices like PDA, and power supply for LSI

including CPU and ASIC
