L6920DC中文资料同步整流器升压转换器数据手册ST规格书

描述 Description

The L6920DC is a high efficiency monolithic step up switching converter IC especially designed for battery powered application.

Package is MSOP8 in order to minimize PCB space. It requires only three external components to realize the conversion from the battery voltage to the selected output voltage.

The minimum output voltage is 1.8V: suitable to supply the most advanced ASIC and μP.

High switching frequency allows for a low profile, small sized inductor and output capacitor to be used.

Reference voltage, low battery detection and Shutdown are provided together with over current, over voltage.

特性 Features

• 1.23V reference voltage available
• Switching frequency up to 1MHz
• Reverse battery protection
• Low battery voltage detection
• 0.8V start up input voltage
• Internal synchronous rectifier
• Up to 5.5V operating input voltage
• 3.3V and 5V fixed output voltages
• 550mA minimum input current limit
• Adjustable output voltage from 1.8V to 5.5V

简介

L6920DC属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的L6920DC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。
