LM2611BMFX Description

Short technical summary and product information.

The LM2611BMFX from Texas Instruments is a current mode, PWM inverting switching regulator. It is designed to operate from an input voltage range of 2.7 V to 14 V, capable of producing a regulated negative output voltage.

 

This regulator features a switching frequency of 1.4 MHz, which allows for the use of physically small and low-cost inductors and output capacitors. High efficiency is achieved through the use of a low R DS(ON) FET. The device includes a shutdown pin to conserve battery life when not in use and a negative feedback pin for simple output voltage setting.

 

Key specifications include a switch current limit of 1.2 A, a typical quiescent current of 1.8 mA, and an operating temperature range of -40°C to 125°C. The LM2611BMFX is available in a compact 5-pin SOT-23 package, suitable for surface mount applications.

 

Cycle-by-cycle current limiting and internal compensation simplify the use of the LM2611BMFX in various power management applications requiring an inverting output.
