# LM2611BMF/NOPB (Component)

## Description

Cuk Switching Regulator IC Negative Adjustable \-32V 1 Output 900mA SC\-74A, SOT\-753

The LM2611BMF/NOPB is a 1\.4 MHz current\-mode PWM inverting Cuk switching regulator for generating adjustable negative output voltages from a 2\.7 V to 14 V input\. It integrates a low\-RDS\(on\) DMOS switch with a 0\.9 A current limit and supports applications such as LCD/CCD bias, GaAs FET bias, and positive\-to\-negative voltage conversion\. It is housed in a 5\-pin SOT\-23 package and operates from \-40°C to \+125°C\. \#TexasInstruments \#LM2611 \#CukConverter \#SwitchingRegulator \#VoltageRegulator
