概述

Description

The LM2776DBVT is a charge pump voltage inverter produced by Texas Instruments. It is designed to generate a negative output voltage from a positive input, making it ideal for applications needing negative voltage rails. The device operates with an input voltage range of 2.7V to 5.5V and provides a stable output of -V_in. It features a high operational efficiency, low noise, and a small form factor, making it suitable for portable and battery-powered applications.
The LM2776 is housed in a SOT-23 package, which is compact and allows for easy integration on PCBs. It has a maximum output current of around 250 mA, depending on the input voltage. This inverter also includes built-in protection features such as short-circuit protection and thermal shutdown to safeguard the device and the application in which it is used.
Common applications for the LM2776 include powering operational amplifiers, data converters, and other devices that require a negative supply voltage in systems that primarily operate on positive voltages. Its efficiency and small size make it a popular choice in compact and efficient design requirements.

Features

The LM2776DBVT is a switched-capacitor voltage inverter designed to efficiently generate a negative output from a positive input voltage. Key features include:
