LM2611BMFX/NOPB Description

Short technical summary and product information.

The LM2611BMFX/NOPB from Texas Instruments is a current-mode, PWM inverting switching regulator. It features a Cuk topology and operates with a switching frequency of 1.4 MHz, allowing for the use of physically small and low-cost inductors and capacitors.

 

This device supports a wide input voltage range from 2.7 V to 14 V and can produce a regulated negative output voltage. Key electrical specifications include a switch current limit of 1.2 A and an output current capability of 900 mA. The quiescent current is typically 1.8 µA, and it offers low shutdown current.

 

The LM2611BMFX/NOPB is housed in a compact 5-pin SOT-23-5 package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 125°C.

 

Features such as cycle-by-cycle current limiting and internal compensation simplify its use in various designs. The negative feedback pin allows for easy output voltage setting with just two resistors.
