LM2611BMF Description

Short technical summary and product information.

The LM2611BMF from Texas Instruments is a current-mode, PWM inverting switching regulator utilizing a Cuk topology. It operates with a switching frequency of 1.4 MHz, enabling the use of small inductors and capacitors. This regulator is capable of producing a regulated negative output voltage, with an example showing -5 V at 300 mA from a 5-V input.

 

Key electrical specifications include an input voltage range of 2.7 V to 14 V and a switch current limit of 1.2 A typical. The device features low quiescent current (1.8 µA typical) and low shutdown current (<1 µA), making it suitable for battery-powered applications. The operating temperature range is -40°C to 125°C.

 

The LM2611BMF is housed in a compact 5-pin SOT-23-5 package, suitable for surface mount applications. Its design incorporates features like low R DS(ON) DMOS FET for high efficiency and cycle-by-cycle current limiting for simplified use. The adjustable output voltage is set using a negative feedback pin with two resistors.
