## Description

The LM2611AMF/NOPB from Texas Instruments is a current mode, PWM inverting switching regulator. It operates from a 2.7-V to 14-V input supply and can produce a regulated negative output voltage up to -36V. This device features a switching frequency of 1.4 MHz, enabling the use of physically small and low-cost inductors and capacitors.

Key electrical characteristics include a wide input voltage range of 2.7V to 14V, an output current capability of 1.2A, and a low shutdown current of less than 1 µA. The regulator utilizes an input and output inductor for low voltage ripple and RMS current on both input and output. High efficiency is achieved through the use of a low R DS(ON) DMOS FET.

The LM2611AMF/NOPB is available in a compact 5-pin SOT-23-5 package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C. The device includes a shutdown pin for power saving and a negative feedback pin for regulation control.
