BD8313HFN集成电路（IC）稳压器-DC-DC开关稳压器规格书PDF中文资料

General Description

The BD8313HFN can produce stepped-down voltage from a power supply composed of 4 batteries, which can be Li2cell, Li3cell, etc., or from a 5V/12V fixed power supply line. Output voltages include 1.2V, 1.8V, 3.3V, or 5.0V. This IC allows easy production of a compact power supply since its high operating frequency of 1.0MHz requires small-sized external inductor and capacitor and the phase compensation components are integrated in the chip. The built-in synchronous rectification switches are capable of withstanding 15V.

Features

■ Built-In Pch/Nch Synchronous Rectification SW Capable of Withstanding 1.2 A/15V.

■ Built-In Phase Compensation Device between Input and Output of Error AMP.

■ Built-In Soft-Start Function.

■ Built-In Short-Circuit Protection with Timer

Application

For Portable Equipments like DSC/DVC Powered by 4

Dry Batteries or Li2cell and Li3cell, or General

Consumer-Equipment with 5V/12V Lines

BD8313HFN属于集成电路（IC） > 稳压器 - DC-DC 开关稳压器。罗姆半导体集团制造生产的BD8313HFN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。
