LM2776DBVR Description

Short technical summary and product information.

The LM2776DBVR from Texas Instruments is a CMOS charge-pump voltage converter designed to invert a positive input voltage, ranging from 2.7V to 5.5V, to a corresponding negative voltage. This device utilizes three low-cost capacitors to deliver up to 200mA of output current, eliminating the need for inductors and reducing cost, size, and electromagnetic interference (EMI).

 

With a low operating current of 100 µA and efficiency greater than 90% at most loads, the LM2776 is well-suited for battery-powered applications requiring a negative power supply. It operates at a 2MHz switching frequency and includes features such as enable, light-load efficiency, output discharge, synchronous rectification, and UVLO. The device is housed in a compact 6-pin SOT-23 package.

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V and a maximum output current of 200mA. The output voltage is fixed and unregulated, inverting the input supply. The operating temperature range is -40°C to 85°C.

 

This surface-mount component is ideal for designs where space and power efficiency are critical. Its inductorless design simplifies board layout and reduces component count.
